I'm just going to say.... you pay for what you get. 200 bux to me is going to sound like shit. I would wait and spend the extra 2-300 bux for something quality such as, Greddy, Apex, Tanabe, Thermal, and RS*R.
If you still have your stock cataliytic converter, use it. If your stock cat is clogged then, get on ebay and look for a Carsound Catalytic converter, or
www.mufflertech.com and grab one from them.
