I would figure they wouldn't make one for my car but I found one on ebay but it is only for a 2door lx. I thought that since the cat placement is on the exhaust manifold than it would be pointless to make one. But I found that one so I have a sedan, would they make one for the sedan?

 

just get an EX header, a high flow cat, and a sedan EX catback that'd be better anyway

 

get a new intake manifold while you're at it.
