Jason, a catback only system will not help you feel the full potential of the 4G63. Here is a site the did a BR catback http://www.twingles.com/ideck/wheels/brcatback.htm
I would suggest to install a downpipe with an O2 eliminator and free flow cat. Visit your local muffler shop and confer with them on building a free flow exhaust system from turbo to muffler.

Do you have an intake system?

ummm all Cat backs for your car will bolt to the stock cat, thus the name, Cat Back. it goes from the cat back, and doesnt mess with the stuff before it.

Well. all of the catbacks i have seen say they mount up to a 2 1/2 inch flange, the stock one is about 1 3/4 so it will not fit, i had a downpipe but i took it off. thanks
