Your local muffler shop would probably be a good bet. Also, check out this study on catalytic converters posted earlier by Zebrahead http://www.installuniversity.c...1.htm .

Correct me if I'm wrong; but he'll probably want an aftermarket exhaust . . . kinda defeating the point of having wider pipes if you have a bottleneck at the cat. Either way, he'll need flanges to make it fit . . . sounds like a hastle :rolleyes. Just get a test pipe ^ ^.Ace wrote:You can use the stock 240 SX cat, instead of buying a new one.
