I know on my trans am, I took it off and it freed up some hp..thanks guys...

Re: Do I need cat. converter.
Where do you live?
Cats generally suppress power... but in some States it is illegal to remove them (like in California where I live).

 Check http://www.3sxperformance.com/exhaust-tt.asp about halfway down you'll see the Ultra-high-flow-cat. I've heard some pretty good stuff about that one.

Re: Do I need cat. converter.
It all depends on where you live, but I'd HIGHLY suggest getting a high flow cat... I know stealthee's gonna' call me a hippie tree hugger, but I really hate it when people gut their cats, becuase it exposes the environment to really bad exhaust emissions....
If you plan on going to a 3" aftermarket exhaust in the near future, than get a 3" high flow cat for it too, but if you plan on siticking with the stock exhaust, than it might be kinda hard finding a high flow cat, becuase IDK if they come in 2.75" ...

Re: Do I need cat. converter.
nah, im gonna beat Stealthee to it, tree hugger. There are only 2 reasons to have a cat.
1) you care more about the environment than George W. 2) you live in a state where they do emissions testing during inspections
