Hey Guys Im running a S4 NA, with just aftermarket filters & Exhaust.

I have been looking at the RB Headers and Exhaust.

Now DO I have to get Both or can I bolt in the RB headers and use the exhaust I have right now?

And does anybody got a vid/sound clip of the RB heads/Exhaust on their FC so I can hear what it sounds like.

Thanks

well.... youll have to get everything racing beat up intill the cat back.

go with the cork sport.

katkaroto

well, i think it will fit if your exhaust system is still similar to the stock set up. headers to cat, cat to y pipe, y pipe to exhaust tips.

No, see the post above you.

katkaroto

well, he never stated aftermarket exhaust setup, just after market exhaust.

TongassT

No. The RB header will not bolt up to stock cats (or anything similar shape). You need the RB presilencers (or something custom) between the header and the catback. Just as SirCygnus pointed out.

this may seem like a dumb question but Were is the cat located and what does it look like?

Thanks

Everybody has to start sometime. There are two on a TurboII, three on an NA (at least S4). They are located shortly after the exhaust manifold, and before the y-pipe. They are 6-sided polygon shaped, can't miss 'em.

You'll have one main cat (the larger one) and either one or two pre-cats that are smaller.
