I just bought a Corsa Touring exhaust system for my 07 EXT and it's too quiet. Only barely louder than stock. I wanted something that sounded a little more aggressive. I believe the only difference in the Touring and Sport systems is the muffler. Does anybody have the Sport system and want to quiet theirs down? I might be willing to trade mufflers with you. Thanks.

The only difference is the muffler, I switched a Sport for a Touring, try the GM Truck Forum, it's the same system on the GMC SUV using the 6.2
