That is what I am going to start calling the LLY after the install of the KD 4-into-5 exhaust on the truck. The 5 inch pipe back from the muffler sounds really cool at idle. It has a really distinct hiss / jet sound that steps right up to nice rumble with some great turbo whistle when you whack the throttle. :D

The install was pretty easy, all the prior threads on killing kitties and such made the removal a cinch even without a lift. The stainless band clamps with the kit make for a great seal on the seams, absolutely no leaks. :cool:

The stock system is really restrictive, no news there but the cat makes it even worse. The truck is running really peppy, it picked up a good gain by the sotp meter and I love the sound. :ro) I even ran it around with the windows down in the 30 degree weather to hear that turbo music. The LLY sounds quite a bit different than the LB7 but I like it. :ro) I did some boosted launch tests, the LLY comes out of the hole pretty good so I might be able to make a race and tow truck outa that sucka. :cool:

Now I gotta figure out intake mods and gauges so the real power adder playing can begin. :D

That have a straight through type muffler? How loud is compared to MBRP or banks or straight pipe? I gotta do something to my exhaust but I haven't decided what yet. Probably straight pipe it first and see how it sounds. I have the front pipe with no kitty from a LB7...

Straight through type muffler with louvers. The truck is louder of course than stock, but not overly so. I have not heard any other LLY systems yet. It has no resonance at any point in the RPM range and I think it will mellow out a bit once it seasons in. The 5 inch pipe is most definitely louder than a 4 inch system. Overall I find it very comparable to my Banks 4 inch on my LB7.

The straight piped trucks sound pretty cool but tend to get a bit overbearing when towing. This system might be a good compromise for you but exhaust systems are very subjective. This one works for me!

As long as Peaches likes it......you are good to go............):h

If Brandon's past posts are any indication, Peaches was writing the check, saying "more power is good".....
