Hey guys, My father in law just got an 08 Denali truck and he's wanting to put new exhaust on it. Im trying to talk him into getting some LT headers as well. He wants the exhaust to exit on the passenger side right after the rear wheel. He dosen't want it really loud either, but he wants it louder than stock. What brand of headers will work best and what mufflers should i use? Anybody got pics or sound clips of there setup?

 

Corsa has been my favorite, especially in that exit location, with the dual tips.

LT's will make it louder, regardless.
Get a catted midpipe, if he isnt wanting it too terribly much louder than factory, then the Corsa catback I mentioned above, or go to an exhaust shop and have a catback fabbed up.

hooker Aerochambers sound pretty good too, and arent too loud.
