I just installed the 4" exhaust system from Pinnacle and it was way beyond my expectations for a 300 dollar system. It went on very easily with absolutely no fitment issues. The hardest part of the whole install was getting the old "crusty"-:t system off, once that was done everything litterally slid into place. I thought video/audio would better describe the end result, so heres the link.

Hopes this helps anyone who is contemplating getting a newer bigger system. I have no regrets about installing it as it sounds awsome and as you can see in the end of the video I can now do a little burnout):h with little effort which it would never do without this upgrade.

damn sounds good! what series is it if there is one? you said around 300 which is pretty damn good. Did you have a down pipe added or anything or is that the stock one? did you get it online? if so could you give me the web page please. looks like somthing i could get in summer......

sounds good do you always have to crank that long for the motor to start

Sure thing got mine at http://cgi.ebay.com/ebaymotors/Chevy-6-5-1992-1999-4-Diesel-Exhaust-by-J-Jardine_W0QQcmdZViewItemQQcategoryZ33630QQitemZ802 5545597QQrdZ1QQsspagenameZWDVW

It was 270 dollars plus 27 for shipping. It came with a downpipe(not the best i have seen) but pretty darn good compared to the one it replaced(it went in very easily compared to what other people have said about their installs and I did it with only simple hand tools with exception to the sawzall, however for 270 bucks it seems like your robbing the man selling it all. It came within a week after I ordered it.

Yes I do but only on the first start of the day or after I wait to run it for about 5 hours. It is a problem That I have chased to no avail even after I changed the glowplugs yesterday. Got any suggestions I would love to take that extra load off of the starter. Thanks

I'll put in a vote for injectors, and I know BCBOGGER will put in the same vote. I'm in the same boat as you, long crank time.

Thats the conclusion I have made also but I want to make sure before I dump 70 bucks to get them tested just to be told they're ok :mad: then I would have nothing for it. Is there anything else I can check. I think the glowplugs are working ok as I just changed them all yesterday unless you guys think that are not working right(puff of smoke at start up maybe:confused: ) Thanks

Might give the lift pump a check too. If the injector pump has to suck in the fuel instead of being fed it, it may account for the delay in firing up.

Are the connectors on the glow plugs nice and tight?

I know the lift pump works good and strong after I opened the water bleed valve and got sprayed in the face. You mentioned the conectors and they are definately lacking in the good conection department and will get replaced as soon as I get around by Radioshack. Would that cause the difficulty starting with little or no white smoke?(I hope so the connectors are nice and cheap) Thanks

dang, that sounds like a friggin semi! I love it!

Very nice!!!!!

Is it possible that I could have hurt anything after doing that sorry excuse of a burnout-:t . Just want to make sure its ok before I go showing off and drop the tranny or something. In my mind a tansmission that can pull more than 6 tons should be strong enough to do what I did in the video when the truck is totaly empty but I am sure I am wrong in assuming this. Thanks

Sounds really nice. I thought the starter was spinning very slow but am I the only one that feels that way? My suburban spins a lot faster even at 10 degrees F. Maybe that is why it takes you so long to start? Am I the only one that thinks that it's cranking a little slow?

I always thought it seemed kind of slow but I though I was just being paranoid. I have never been around another 6.5 so I have nothing to compare it to. Is there any way to test for the correct speed.

I would have to agree with guy, starter is very slow compared to mine, check your cables and do a load test on your batteries.

Watch the tach while cranking maybe? I think the 6.5 is supposed to have a minumum of 250 RPM's to start though.

WOW mine does not sound even close to that but I have never looked at the tach when starting; Never knew it moved while starting. I will check it tomarrow.

I'm in for the batteries idea. Might be getting weak. How old? Mine would let me know when they were on the way out, slower cranking and longer crank time.

Sweet video. My turbo doesn't quite make that much noise in park. Must be that extra 1" on the pipe. I love the first burn-out. The slamming on the brakes just after it left the camera was priceless!!:grd:

Here's a video of mine starting up.

I'm jealous now, I wish mine would start like that:( .

Do you have a modified air intake system? I didn't see one on your sig. That is about how my Suburban sounds with just deleting the kitty and straight piping it out the back and an open air intake system on it. Awesome by the way. I now occasionally now let my wife drive it so I can hear the truck take off down the road!! Had a guy stop me in a C store the other day with nice comments on how he heard the trubo coming from 2 blocks away.:ro)

Nice video. How's the interior noise level?

I have been looking at the exact same exhaust system off of Ebay, seeing how my exhaust is just barely hanging on. I know for a fact I will order one now. Man that thing sounds wicked, I luv that turbo sound. I have 3 in. exhaust, but as of yet, have never even heard my turbo spooling up and down. Don't feel bad, my truck starts slow too. Shrugs, figure as long as it is starting, will let it be until it becomes a bigger issue.
:ro)

It is about 30 deg. F here this morning and I listened for cranking speed and it is definitely faster than in your video LL. Time to start looking at stuff.

I am convinced after that "starting" video that mine is definately slow. I guess I will have to take the batteries to get them load tested. Actually my intake is completely stock right now. As for interior noise there is only a slight rumble and turbo whine on hard accecleration and you cant even hear it at idle. It is however much louder outside. There is also no more droning that I used to get with the stock system wich I am thankful for.

I'd be further inclined to guess your starter is going south. Check your batteries first because it's free. If you have strong batteries, then I'd say you're in need of a rebuild on that starter. I'd recommend Carlton's in Upper Sandusky (not far from you), unless you're wanting a "new" one. Their starter guy is good. He rebuilt mine about a year ago for under $100. PM me if you need the address and more info.

SnowDrift

You're not going to be able to watch the tach to see if it is running at 250 RPM unless the truck is newer than 94.

EDIT - It is a 94 isn't it ?

Its a '95

My truck starts about the same as yours, lanieluke. I just thought that was normal...

Sounds awesome btw.

Mine turns over quick as all get out now(I'm on autozone starter #4 right now:eek:), but is as slow as lanielukes to start. Really need to get them injectors replaced:o:.

That sounds wicked! Now I definately gotta do that... but maybe modify it to duals with 5" or 6" tips.

luke, what ever happened to that pull competition you were going to have with that guy? I'm pretty sure it was you who was asking for advice on that.

Ferm, I think my injectors may be going too. Thats the only thing I can think of as to why I'm having cold start issues. It puts a nice puff of black initially but then immediately runs like crap the next few seconds. My theory is the glow plugs have done their job but starting to cool off and the engine is still cold so it therefore relies on good spray pattern from injectors until it warms up some (am i wrong?). How does yours start warm (after shut off for an hour or 2)?

i know that the truck exhaust system sounds god, but the increased sound of the turbo, doesnt that come from the better downpipe? juts wonderin.....

No, I only upgraded my downpipe and crossover so far on my suburban, and the downpipe didn't change the turbo sound at all. It did however improve the power a little (noticeable at least).

I think I want this Pinnacle exhaust now. For the price, I couldn't fabricate my own for less, so might as well go for one already made. My only concerns are:

1) since I already have a Flowmaster downpipe on, I don't need the one that comes with the Pinnacle system, however, I don't think the Pinnacle exhaust pipes will bolt up to the stock downpipe flange, but maybe I could just cut the flange off the Flowmaster downpipe and clamp the pinnacle pipes on there. I would rather not remove the Flowmaster downpipe if I don't have to.

2) I am concerned about the noise inside with a 4" on my Suburban. From what I understand, a 4" doesn't have too much cab noise on a pickup, but it can be very loud inside a Suburban. Anyone have this exhaust on a Suburban? Is it too loud?

My goals with upgrading the exhaust are:

1) Improve fuel economy by 2 MPG or more.

2) Improve power noticeably

3) Improve sound quality with noticeable turbo whistle and a little V-8 rumble, but not at the expense of interior noise and drone.

Same question I have Stingray. My 'burb is my wife's daily driver. She'd pitch a fit in a hurry.

I did go catless and staight pipe on my Suburban; however the piping is stock in size with stock downpipe. Sounds awesome on outside, not noticeable on inside. Turbo screams with that mod and the SS Diesel air intake system. Didn't gain much, if any, power and no gain in MPG's from what I have been able to tell so far. I guess now I want to upgrade to preferably a 3.5 inch system. From what I have heard from other Burb owners, 4 inch is really loud inside. Kennedy says 3.5 does the same for power and MPG without added noise. Would like to also hear from other Burb owners who have upgraded from stock.

FYI: Previously I was running a stock exhaust with the muffler and cat cut out and replaced with straight pipe. It was a little louder than stock, no doubt, but very tolerable.

Recently I replaced everything from the (3" Flowmaster) downpipe on back with a 3-1/2" system from a duramax. It's noticeably louder than the previously straightpiped stock (2-1/2") system, especially in the area of the downpipe, and there's a little more drone at highway speeds. But it's still very tolerable and the little bit of giddie-up and increased turbo whistle makes it well worth it.

It's pretty cool when you flip the hi-idle switch and can hear the turbo spooling up.

Stingray/Steve,

I'd say buy it get a set of ear plugs, or turn up the volume on the radio :D , yeah I know probably would not work, but I would try it 1st save the old system and swap back if it became unbearable, and sell the system for what you got in it, it's a risk you might have to do the work twice, but IMO such a good enhancement and start of the building blocks needed for more power.

Sell it on the mpg economy of it to her (may or may not see it unless running at 55 mph), also you may be able to add sound dampening mat if really unbearable, I don't think it would be that loud however.

Mine does just fine with the Banks 3.5" so 4" may be overkill

Anyone ever tried the Aero-turbine muffler? I 'm going to put a 4 inch and one on my dually this week. Its looks neat but was pricey!!! My son has one on his Duramax and loves it. So I bit the bullet and bought one.

The pull "competition" pretty much dissolved for some reason. The other guy was to busy and I guess He got caught up in some other business. I just ordered a 4" to 5" tip from summit racing for 30 bucks and it arrived yesterday. It is an exceptional quality polished stainless steel tip to finish off my exhaust and it was about half as much as any other tip of this size I have seen. I have a question about my startup problem. I know it cranks slowly and I have yet to test the batteries but once the truck gets started it does not smoke at all untill it has been running for about 3 or 4 minutes then you can start to see a stream of white smoke(smells like unburnt fuel) comming out of the tailpipe. Is this indicative of an injector problem or should I look elsewhere? This also reminds me of what I found strange when I was putting the new downpipe on; there was a wet(felt like a light oil wd-40ish)residue inside the old downpipe and inside the turbo outlet? Any ideas?
Thanks

I'd love to find a 3.5" at the cost of Jardine's 4". That's the primary reason I'm looking at the 4" systems on ebay. I don't know much about diesels, but I know on a gasser too big of an exhaust is a:badidea:

Is that the one that supposedly draws exhaust out, several of us over on the other site I hang at when it 1st came out, we had some serious reservations about the claims they make about it's scavenging ability.

Some real Doc's (I just play one like a field medic is called a Doc) with PHD's and been there done that (don't need no steeking turbo types) in Engineering disciplines like thermo & fluid dynamics and a host of other shingles, were rather critical of Hp gains possible claimed by the vendor.

Do you have dyno or other data from before & after, consensus was there that a properly sized conventional "opened up" system would net same Hp gains for less $$$

Diminished return anything over 3.5" has been consensus, little if any net gain.

Check your timing for your slow start problem.

Upgrade or check battery cables too.

Different animal because our engines are blown. Bigger just gets more expensive (sometimes) and harder to fit (sometimes). I like the sound of my 4 inch just fine and I'm am old guy, not a youngster like some of you high school guys here.:blahblah:

I concur. I just can't find 3.5" systems for same $$$ as 4". Plus, we are in a size-is-everything society- everybody buys the bigger is better hype (speaking of car stuff fellas, I know what you're thinking:rolleyes: ).

I can't tell you how many jacked-up club cab work truck diesels I see around here with 5" systems on stock engines. All that noise...

OK, thanks for the advice. Another question though:

Most of the people saying the 4" exhaust was too loud inside a Suburban were using a straight pipe with no muffler. Since this Pinnacle system has a 4" muffler, would that be better? If it is too loud, could I just get a bigger 4" muffler to make it quieter? Or is it the fact that it is a 4" system that makes it unavoidably loud even with a muffler?

Is the Pinnacle 4" with muffler louder than the stock system straight piped and no cat?

I actually have no interest in a 4" system, and it still makes no sense to me to have a 4" exhaust with a 3" downpipe as the downpipe is the weakest link. However, the price of this 4" system, and the fact that it is complete and ready to bolt on is what has me interested. I was going to fabricate my own 3" system with universal tailpipe kits and muffler, but this would be much easier. If Pinnacle offered a 3" system, I would definitely get that instead of the 4".

Is bigger better? Sure! Sometimes space is the only issue. I'm running a 3.5" and it might as well be straight piped because I can drop a golf ball straight through the muffler.

Noise? Not really noticeable in the cabin. Sure lower RPM's you can hear it but at highway speed it's quiet :) , unless you want to jump on it :ro) .

The most important gain is it getts rid of more heat. I dropped 100* on the pyrometer at highway speeds.

Just got my ss diesel 4inch on and sounds great only time any louder is when your on the throttle. cruissing not any louder. very simple install. im in love

I don't know much about diesels, but I know on a gasser too big of an exhaust is a:badidea:

uh oh, I run open headers on my Vega:eek: ):h

So am I. It just seems like the ULTIMATE upgrade over the stock exhaust and it is relatively cheap, now with the new 4" system my truck sounds like it is running on all cylinders like a good v-8 should:ro). Now I just need to save up for a performance chip(how can a little e-prom chip cost more than a 4" exhaust system:confused: )

uh oh, I run open headers on my Vega:eek: ):h
On a race car, sure! But you wouldn't put 2 1/4" primary headers with 6 inch exhaust on a stock 350. You'd lose major low-end torque. My only point!!!:D

Just finished installing the 4 in. exhaust. From the flange at the down pipe into a 3 in. to 4 in. adapter straight pipe to high dollar Aero-turbine muffler straight pipe to tail pipe from Jardine. Used stock hangers just cut off the stock pipe. Changed from straight 3 in. pipe from flange to stock tail pipe to new 4 in. system. Its considerably quieter now, probably the straight through muffler, with a deeper tone. Before it sounded like a glasspack. Performance wise I haven't pulled anything yet but did notice QUICKER throttle response. If I were to do it again I'd probably get the Jardine muffler ($70) instead of the Aero-turbine. The Aero-turbine is by far the best looking but right now thats all I see.
Cost: 10 ft. straight 4 in. pipe - $44
Jardine tail pipe and adpt. - $90
Aero-turbine muffler -$250

I have the pinnacle/jardine unit with the muffler in my suburban. The exhaust noise is not bad at all. You can have a civil conversation while cruising, keep the radio at the lower end of the adjustment, and talk onto a handsfree cell phone. About the only time you know that there is a noticable exhaust note is at idle (definitely not stock :) ) and when your stepping into the "go" pedal for acceleration and passing. Other than that it basically drowns out the road noise created by the stock toyo tires I am running. About the only thing I didn't like (personal preferance) on the exhaust was the honeymoon hard on exhaust tip, man it stuck way out there. Camping world had this nice 4" stainless turn down tip on sale. It directs the gasses down, away from my house and is quite nice looking for my tastes and needs.

just got my ss diesel 4" kit on, way better sound):h but the exhaust is hitting the cab or something, rattles at about 900 rpm but gett'r fixed monday. think the rear brakes are set to hard cuz she dont wanna light em up till 5lbs or more of boost come on. Overall impressed with the kit and contents muffler seems decent quality

I am just curious where you got the 10' of 4" pipe at? The muffler shops around here don't mess with that stuff and don't carry it. Would luv to just run str8 pipe out the back with no muffler.

Would luv to just run str8 pipe out the back with no muffler.It's a kit sold on ebay by Jardine Exhaust. You could search for their site on the web and order direct from them and probably save a few bucks on shipping.

You could also order 4" pipe in I believe 5' lengths from Summit Racing.

Oh, and I had a buddy at an exhaust shop cut the cat and muffler off the stock system. I really don't care for it much... sounds like a big block with 2" exhaust and glass packs-:t thought it'd hold me over till I order a 4" kit but I guess I was wrong:mad:

Hey dwayne, I bought my pipe at the local NAPA store. :cool:

NAPA??!! I will check with them tomorrow and see if they can get it for me. I already have a 3" down pipe, all I need to do is run pipe back to axle. Wasn't really concerned about going over the axle as I never put a topper on the truck. It looks as if a str8 shot of pipe will work fine under there. Only issue will be adapter from the 3" down pipe to the 4" exhaust. Appreciate the input. :ro)

Wow, I can't believe there isn't a muffler shop in your area with 4" pipe and a mandrel bender. I'm 50mi. SE of seattle and I can think of 4 right close to me that do 4" exhaust. It would look cool and sound great without a muffler!!:D

Ramsmoker,

There aren't any around here that I know of that can bend 4" exhaust either.

To those asking about the 4" system on a Suburban. I have the same 4" Pinnacle system on our Superburban. It has the muffler, although it is like looking through a straight pipe. :ro) It sounds very good, and we do not notice any noise inside unless getting on it. :cool2: It is the wife's daily driver and she loves it.

This is VERY good news as our Sub is my wife's daily rig. I'm ready to put one on it now!

The Sub is my wife's daily driver too. She loves driving that rig. Anyhow I put a 4" Pinnacle Exhaust with magnaflow muffler on it and it rocks! I love my 6.5 TD Yukon, but it sure is fun to drive that F engine Suburban from time to time.

if anyone is still on the slow start, i feel the same way that mine starts really slow compared to the video put on here. but i just put a brand new lift pump on and 2 brand new interstate batteries and still hasn't improved any. guess i'll keep trying.

Your truck cranks even slower than the video?

i don't know that it is any slower that Luke's in the 4" exhaust video, but it is definetly as slow. mostly when it is cold out and/or it sits for an extended amount of time.

Well I just had the batteries checked and they both passed with flying colors. I was hoping it was the batteries because they are cheap and easy to change, but I guess I will have to look elsewhere:((starter?)

but I guess I will have to look elsewhere:((starter?)
I would think cables, grounds and connections first.
