you'll love the sport sustem. It rocked on my 04'.

 

That is a VERY nice exhaust setup.

 

when do you plan on going to the track and knocking off your first 13 second run?

 

Not starting a war, but no way would I take the cats off! I had mine off for awhile and I hated the tin-can sound you get when you give it some throttle. It even had this crazy whistle at WOT. It is much nicer with the cats back on.

I have heard the Corsa Sport on a Denali truck with some long tubes and no cats before and I didn't care for the sound. The guy that had the truck wanted his cats back on in short time.

In terms of flow, I would think that the Dynateck cats will flow better than the stock ones. I am convinced that my Carsound cats flow much better than my stock ones did. Oh, and that darn whistle is gone!
