Hey guys,

I am looking at getting a cat back exhaust for my S15 but I have a few questions.

1. Is it worth going cat back? Can I finish the whole lot later with no problems? ie: turbo back

2. Is there a performance gain from cat back or just noise really?

3. Is there a difference between mild steel and stainless steel?

Thanks guys!

Josh

The cat back will give a worthwhile power gain and it is a bolt up so you won't have a problem doing the front/dump and cat later on.

Mild steel is fine. Performs the same but doesn't have the pretty shineyness of stainless (not that you'll see it once it's covered in road grime) or the price.
