I am interested in knowing if anyone has installed any of GM performance exhausts that can be purchased from the Dealerships? If so, I would like to know what your overall thoughts, installation and if you experienced any increase in performance?

Thanks

I have not, and probably would never either. Have no idea on the price or any specs.

I'd just go with a quality aftermarket company such as Borla, Gibson, Dynomax, and so on.

If you want to get a not so loud rumble but much better then stock then do what I did and swap out the stock muffler for a Borla Turbo muffler.

I've heard that some dealerships are offering the Corsa exhaust package, but its one of the most expensive catbacks out there. On a stock/lightly modified truck, its probably the best sounding catback available.

Slow is right, they are definitely proud of their systems as far as cost goes!! But, it has an awesome sound! Here's the link:

Man it sounds good...my Borla works and sounds great but it does have some rumble in the cab...I wonder how Corsa gets rid of it (the rumble).

Corsa is an exellent system. My cousin had it on his modded Z28 and it's the best sounding camaro I had ever hear. Okay, so he had a cam too. But then he wrecked it and has a T/A and his dad won't let him put it on so it's sitting in his closet.
