Re: 2.5" Cat vs 2.5" Test Pipe (Dr Pooface)
If there isn't much of a performance difference b/w the High-Flow CAT and a TestPipe, then I wonder how effective that CAT really is at "keeping the environment clean". Probably not much, so it's just a matter of keeping it legal.

I got more power using a Carsound cat. (butt dyno). I am personally more happy with the carsound cat. Plus when my roommates drive behind me they don't pass out.
