Title says it all....let me know thanks

To answer you question directly, NO. I have a MBRP aluminized when look used when I bought it from a major supplier and doesn't fit well (IT is quiet). Funny thing is my friend bought one of the cheap and cheerful ebay units for over $100 less delivered, and it fits better, looks better, and was new and clean. Don't always get what you supposedly pay for.

no, but the Summit aluminized "turbo back" aka downpipe back is great! I think it is also cheaper.

I have Jegs 4 " exhaust and I like it. It was cheaper when I bought it though, I think I paid $500 for the stainless. Reasonable fit and nice sound IMHO. Pretty good deal.

No experience w/Jegs, but I have the Summit 5" system. I didn't use the clamps w/ hangers, instead I built hangers out of 1/2 inch round-stock, and welded all the slip-joints. I didn't use the muffler either (I don't like louvered mufflers) I used a 26" Donaldson muffler in its place. It was easy to do and now I have a one of a kind system that sounds good and lowered EGT's another 80-100 degrees over my old 4" system. The system came in a torn up box and all the ends of the tubing were dented up. But I couldn't complain as Summit only charged 5 bucks to ship it and I got it in two days. I just used a cone off the tire balancer and a rubber mallet to fix the ends of the tubing.

Ditto that on the thumbs up on Summit Exhaust. It's identical to the MBRP exhaust my buddy bought and cheaper, too!!! good fit out the box, but I re-bent a couple hangers and welded joints, too!!!

Ltrain,

You basically get what you pay for as it has always been etc. The lower priced system use a low temp fiberglass to pack their mufflers if they pack them at all, the low temp stuff blows out in a few weeks to a couple of months and then the systems for a lot of folks gets too loud. You would be amazed at the number of replacement muffler we have sold to jegs, summitt etc product owners a few short months after they installed their system. Now add up the cost of that system plus a second muffler and you have spent more than our system to start with. Now not all folks care if it's loud or not so for some that may be the way to go, but remember if the packing material is gone now your muffler is a restriction in your system, not the reason you got a performance system in the first place etc.

Our systems have welded hangers to match up with the OEM hangers, we use a ceramic blanket and stainless steel wool for our mufflers, all of our clamps are plated to not rust after you go thru the first winter time puddle etc etc.

They cost more, not much but you have a $40,000.00 dollar truck there as well, you didn't cut corners when you purchased it or you would have gotten the 8.1 gas engine. As always call us if you have any questions etc and we will be glad to help you.

gardnerteam,

I have asked you before when you have posted that you felt you got a used system and or one that was damaged etc but you have never responded. WHO did you purchase it from? Why did it look used? Are you familiar with the appearance of aluminized tube when it is new? You might have gotten it from us I don't know, but I want to know if you did as we want to make sure all of our customers are satisfied. If you didn't get it from us who did you get it from and what did they say when you spoke to them about your concerns?

Finally I would imagine the manufacturer would be insterested in your concerns as well.
Have you spoken to them? We have sold literally 100's of the MBRP aluminized systems and NEVER had a customer have the comments you have and we want to get to the bottom of it to help you if we can.

This is the picture of the Summit 5" system that I was asked for. I will post some of it on my truck in a bit. Gotta go pay the bills...

http://static.summitracing.com/global/images/prod/large/sum-680006_w.jpg

On edit... the picture on the Jegs website shows the same looking muffler as the one I got from Summit, who wants to bet that they are made by the same place, only for Jegs to charge 499.00 and Summit to sell for 362.00?

So, how loud is the Summit 5" system..? Inquiring minds would like to know..:D

John

I wouldn't be a good one to ask because I put a Donaldson muffler in instead of the one that comes with it. Fairly quiet inside, barks out side. I would guess it to be louder with the muffler that comes in the kit, just two louvered chambers and no packing.

The 5" system by Summit is made by a company called Heart Throb Exhaust and possible the one from Jegs also.

Professional Exhaust in Iowa has a nice 5" that I had on my 02 GMC, the fit was clean and tight. I hope to mount one on my 05 soon

Here are a couple of pics of the Summit 5" installed, Keep in mind I welded most of the joints, made my own 1/2" hangers and used a Donaldson Muffler as I do not like louvered mufflers...

4" to 5" at area where stock 4-bolt flange is located...

one more...

lookin good, thanks for posting the pics!!!!!!

Max, did you change the downpipe or leave it stock?

Do you mean the real down pipe, or the part that people call the down pipe?Max, did you change the downpipe or leave it stock?

Mark -since you asked, I'll tell you where I got my system. I have never mentioned the supplier before because I don't ding suppliers although I will ding manufacturers. I got the system from YOU! We conversed by email about the quietness before I bought it, and I ordered it by phone from someone at DPP, telling them I had talked to you. When the unit arrived, the box had obviously been opened at least a couple of times, no instructions, and appeared to be missing parts. I called DPP immediately and they took my number and said they would get back to me. Layed it out on the shop floor and found it had been mounted before or at least assembled before due to the clamp cradle marks on the pipe where clamps had been cinched up. Unit was dirty, fingerprinted, but no black soot inside so I cannot say it was ever run. No call ever came from DPP after several days. I said screw it (actually, I probably said worse) and installed it. Played with it several hours - poor fit, hung down too low. Drove it. Quiet, just as you stated. Still didn't hear from DPP. Screw it - it now has been modified, fits OK but not as well as Banks I've sold nor as well as MBRP 304 I have seen. As I have stated, a friend bought a cheapie off Ebay for $100 less. It looked better, wasn't used, had instructions, sounds about like Banks (a little louder than MBRP), and he paid well over $100 less. I was not a happy camper with your company nor MBRP. I have NEVER mentioned your or your company until YOU ASKED in this "thread" Ask and ye shall receive"

Do you mean the real down pipe, or the part that people call the down pipe?
The downpipe, from the turbo down to the flange. The real one...

Banks Monster is the way to go.

Banks is just a name. No reason to pay top dollar for the same exhaust pipe..

No, I haven't. I would probably do it if one were available, but I don't think I will try anything custom. Why do you ask? Do you know something I need to know?The downpipe, from the turbo down to the flange. The real one...

gardnerteam,

Glad you responded to me, we have asked before and never gotten any response from you so we didn't know what was wrong or if it even was our responsibility, purchased from us etc.

First thing is no one here ever remembers having any calls about a system that looked damaged/used before, you say you called and if you didn't get a return call for that I apologize. Customer service is one of the few things left in the world that you have 100% control of and we work very hard to make sure we do the best that can be done.

What we would have done is send you another system and or ask you to take some digital pics so we could see what you saw and make a decision to get you feeling good about the system. I still don't know what you purchased from us as I don't have your real name etc only the site name and because of that I can't go thru our systems to see what you ordered. The reason I mention this is we open systems here to insert front pipes, tips, air filters, modules etc etc and then restaple them to save the customers shipping costs. So the system might have been opened here on purpose to add other items in the box for UPS savings. Then again you might not have purchased any of those items, again I don't have your name to check, which means the system was shipped by us as recieved from the factory, or as has been the case a few times in the past UPS has restapled and retaped shipments when they have done some pretty good damage. About the clamp marks I can't answer what that was about or how it happened, occassionally we have a returned system that a customer ordered in error or changes their mind about, these are repackaged if they are "as though new". I have never had a system returned that had been installed so it's a mystery to me where it could have come from, all returns are inspected and we would have seen the clamp marks you mentioned. We have a section of the warehouse that is devoted to returned, less than perfect systems, we put sales on these items to sell them at a discount to wholesale customers only, no retail at all.

Now way to get you an exact answer either way I guess, but I will tell you it is not our practice or the manufacturers to send out product that isn't new, if it got out it was an honest mistake.

I can't fix what is done, but I can extend an offer to you to try and help make up for the problem, our fault or not either way it doesn't matter. If you have any other items that you want to get for your Duramax we will gladly cost them out to you. That way you will not have any, or much less cost in the system and can get yourself something you were planning to get and a much reduced expense. I will also check with the manufacturer to see if they had any returned systems that might have accidentially gotten shipped out as new my mistake. I have already had the manufacturer send you a PM message to see if they could help before I got this post, so as you can see both DPPI and the manufacturer are concerned with your situation.

Again I apologize for the problem, even if it was a problem we didn't cause or have any way to know was going on. But we will try to make it up to you if you will allow us to, call me, we'll research your invoice when we know who you are and see what we can find out, 866-455-7788.

Mark @ DPPI

fyi, the summit stainless exhaust has a different muffler then the aluminized and a coffee can sized chrome exhaust tip.

I have had the summit 4" aluminized for over a year and no problems yet. Even if the muffler blows out i'll weld on a new one for much less then the competition. The fit on it was perfect and took about 30 minutes to install with common hand tools and no lift. The summit stainless exhaust for some reason did not fit all that great on my buddies truck.. Probably due to poor quality control in China.

Now THIS is customer service! When it comes time for me to buy my exhaust, it will be from DPPI!

Mark and I are discussing this on private threads rather than washing dirty laundry here, which was never my intention to do. I never mentioned the supplier of my kit on this board until he asked. I also had never received any contact from Mark or DPP until it appeared in this thread. This case is closed while I work out my problems and concerns directly with the manufacturer whose president contacted me a couple of days ago. As I have always said in every comment I've written over the past few months, the system is very quiet which was promised and the 304 SS system I viewed on another truck looked and fit great.

? for Mark, is your system completely stainless? ie. clamps and hanger rods? I bought a system (forgot manufacturer) for my old gasser, and it was stainless, but the hangers and clamps rusted real bad after two winters (actually rusted away) I had to buy stainless hangers which were not the rod type that insert in the factory rubber grommets--the replacement hanger lasted but did not work as well, and I had to drill the frame in several locations!

redneck45,

If you get our stainless systems all the "welded" hangers that are welded to the tubes are also all stainless, the clamps and clamp/hangers are plated steel. The plating is good for a long time and shouldn't allow corrosion to start for a pretty long time, even then they are 3/8ths rod and the clamps are HD style so having a corrosion failure would be very unusual. Also all of our systems (with the exception of an occassional dual system as sometimes the hole for the drivers tail pipe isn't drilled by GM for some reason) use the factory mounting rubbers/locations so you don't have any welding or drilling to do.

Hope this answers your questions, if not call or post and we'll follow up with you.

Mark @ DPPI

Does anyone know if just the turbo down pipe is available separately and what the part # would be? (5 inch outlet on the pipe) Also, are the LB7 and LLY downpipes the same?

Cummin'_Stroke_this_Dmax.

The front pipes as we call them are the same, the true down pipe (pipe connected to the turbo( is a different item. All of ours are 4.0 inches and have the 4 bolt flange to connect up to our systems or to the stock systems like a lot of LLY guys have done to eliminate the cat only.

Mark @ DPPI

Mark, How much is your system for a 2002 2WD Crew-cab (Stainless)?????

Mark @ DPPI

I want to replace the "true turbo down pipe" so I can put my pyro sensor in then just replace the entire pipe. (keeping my entire OEM exhaust together if needed later on) My goal is to get to 5" exhaust..... so I'll probably have to have a 4"-5" adapter off of the "true turbo down pipe," then run my 5" exhaust the rest of the way? (I'm either going to go with catless single exhaust or true 5" dual stacks up thru the box.... I haven't decided yet.)

02AlliMax,

Well we have cat back and turbo back and T-409 stainless and T-304 stainless as well as duals in both materials etc. So there is a bunch of different options to select from. Call us and or tell me exactly which one you want and I will PM you with the info.

Mark @ DPPI

Cummin'_Stroke_this_Dmax,

Don't take this a trying to tell you what to do, but unless you have a pre turbo pyro already and want a post one as well it's our opinion doing just a post turbo one is a watse of energy overall. Some companies will tell you there is only a 200-300 degree difference, and they are right when you are towing little to no weight and aren't in mountainous terrain. In the mountains you are able to see as much as 600 degrees difference in a pre vs post mount pyro. Mount the thermocouple in the cast iron manifold on the passenger side. If you need pics go to the Edge site and look at thier pics on the installation of the Attitude monitor.

Mark @ DPPI

The 5in system is sweet...If it were me i'd then get an adapter and get a big ole honkin 8in tip...like i see alot of the ole Pete's or K whoppers runnin...ahhhh nothing like the sound of a cat w/ 8in str8's and the jake....sry kinda wondered off there..

but heck yah a 8in tip would be saweet..
