for the reference of DRONE, do not use a truck to decide exhaust for a SUV...they are far different in the cab.

Gibby the only fear with more aggressive is cabin drone. Th rear of a Pickup truck is not enclosed like and SUV. The GM performance system retains one of the flapper valves to help with this.
Thanks, I'll send you my email address.
But I did find
In our '06 Envoy Denali XL, I did the muffler delete and had it that way for 80k miles or more.
I did some searches and it looks like there are quite a few swapping just the mufflers or doing a delete and retaining the flappers.
Think I am going with the delete and retaining the flappers. If I don't like, I am thinking of going with the Flowmaster Flow FX.

I just had the gm performance cat back exhaust installed and it is pretty darn similar to the stock in terms of sound and look. I haven’t really banged it out yet to see performance wise but no drone and looks good but very similar to the stock in terms of appearance and sound.
I also had the chrome emblems removed and all black logos installed which I like and the bow tie mirror ground lights.

Any chance of you making any videos of the Corsa? Am a big fan of Corsa. Can’t wait for them to put out their own product for the 21’s. Dunno why it’s taking so long for the aftermarket guys to develop the exhaust systems for our application.

Thanks a lot buddy. Even still with whatever that can be heard, it sounds like bad ass. Far better than stock at least.
