How much hp does the car make? You'll probably be safe with 3".

Are you asking for just collector extensions, full exhaust single or full exhaust dual?

If you're asking for collector extension length and size, use whatever diameter your current collector is. 14" length is just about the best compromise between added low end power and a nice top end pull. I had heard that and read that a couple of times so that's what I went with.
