Wouldn't order it again. My business partner bought a Denali 6.2 with stock exhaust at the same time as my At4 6.2 so I've had some seat time with both setups.I'd be interested in what you think of the performance exhaust as an afterthought. Would you remove it or order it on the next new one?
The perf exhaust is louder on startup and has a deeper rumble but pretty close to stock in most light throttle situations. On an acceleration romp it has a nice sound if you're into that - but its a little aggressive for this kind of vehicle. My biggest gripe has come when towing or under slight highway load --- at 1500-1700 rpms you get a drone in the cabin. You can force a downshift and it goes away ---but we do 600mi round trips with and without a trailer so its been noticeable.
We also have a 2500hd 6.0 with exhaust so its not like I'm opposed, but overall in this application I'd pass.
