Hey Jason I am a service manager for GM I currently own a 2004 duramax with the lly engine. if you have ever looked at a performance exhaust system there really is nothing ti it. from gm they take the stock muffler and reduce it to 2 1/4 pipe internally and then back to 3" when it leave for noise purposes. I went ahead and removed the stock muffler and welded in a straight pipe in place of the muffler and then took the tailpipe and rerouted to drop down in frt of the rear bumper. then took the stock air box and ported it out with a 1/2" drill and installled a k&n air filter and what a difference. i have not installed a programmer yet but just by doing these small upgrades i improved fuel economy in town to 18.2 city and 22.3 highway. the truck is 4wd with 35" tires and a 6" lift. the speedo is 10mph slow but the truck performs like a bat out of hell. if this is any help dont spend the cash if you dont have two. also the company i work for uses automotive fuel additives made by bg petrospecs the fuel additive is called 248 and it makes another difference.here is california we have issues with our fuels and the 248 puts back in what they take out before it makes it into our tanks.

I did the Edge w/ ati , AFE, MBRP,Its a kick in the azz.Wish I had done it whe it was new .

As far a warranty there a thread on the Diesel site that there was a law suit against Chevy saying it did not void the warranty ,but its going to be a pain and cost ya if ya need it.

I towed in 3 and it gets close to 1350 ,if it does it will defuel so its not going to hurt anything anyway

I am selling my Edge Attitude chip for a Duramax LLY (2004.5 thru 2005). The chip is GREAT, I am just changing it to a programmed ECM chip for the better MPG only. I don't need this much extra HP. (damn that just doesn't sound right...)
