Ok, I just bought a N1 style catback exhaust, and im wanting to buy the downpipe, and header for my car. I got me a good ole' R18, so my question is if I buy all these will they all bolt up directly together?

downpipe http://www.topspeedauto.com/Pr...=1834

header http://cgi.ebay.com/ebaymotors...l1318

 

no. fab is required.

 

Ok well what will I need to do to get it all to work?

 

Or would it be better to just go with the downpipe, or just the header?
