I have a MAC O/R H-pipe and factory Mach 1 cat-back. It's surprisingly loud and it sounds a m a z i n g under moderate throttle outside the car. There is zero drone inside the car and cruising is very manageable. Still, when I get on the throttle it sounds beautiful. I was very surprised what a difference the H-pipe made.

I've been looking at aftermarket cat-backs, but everytime I drive the car I think "this is perfect".

All the other guys in our group run the SLP stuff. Personally I hate it. Sounds raspy and cackly and "cheap" in my opinion.
