Well I found a Type S exhaust to put onto my Base RSX, it includes only the exhaust from the cat back. I have seen in some posts that I need a new header. What type of header would I need? Any replies would be appreciated before I purchase the exhaust. When searching through other threads I see I need a downpipe??? Could somebody explain what exactly I need so I do not buy the exhaust and cannot put it on the car. And if I do need something where do I purchase it ie. header/downpipe.
