I was looking on gm web page at the 09 denali parts list..

one of the company denalies sounds killer with the stock exhaust, its a 07 model.. anyway i noticed they have a "performance exhaust" for it now..

Anyway what im thinking about doing it trying to fab that exhaust up on my 8.1L Mine runs true duels into the muffler and then the muffler makes it into a Y and out the little freaking tail pipe. Ive tried a few aftermarket mufflers, Gibson cat back sounded like poop... its laying in the back yard. then we tried a two different flow master and neither one worked.. one was to small and the truck wouldnt run.. i blame the retard at the exhaust shop for that one. The second one was a 40 or 50 series.. ran good but the drone was way way way to loud.. you almost didnt want to drive it more than a mile..

Anyway if i was to get a dual 3" into what ever size this persomace exhaust is do you think it would work.. my 8100 is a 01 so its the old body style, or do you think i could just the actual muffler...
