Need help with custom exhaust.
Hi guys,
I'm going to custom an apexi ws2 for my sedan. I also ordered a dc race header and was wondering what I would need to do to not get a CEL. The piping is going to be 2 and 1/2 inch. I've searched the forums and found that when installing a race header I would need a spacer or defouler? I'm a noob tech and have no idea what that is...please help me out thanks in advance.
