Miltek fitment question. (do RS4 downpipes fit S4?)

**ieatfishburitos** · 04-19-2008 10:42 AM

Alright, I've got a line on a full miltek system off an RS4. I already have the catback on my S4. The local seller stated that the RS4 downpipes won't fit on an S4. Is that true?

Thanks in advance..

don't know, but are you interested in selling just the cat back portion of the Milltek for the RS4? Is is valved?

Call Stratmosphere and ask them to compare the two for you. I will tell you that the CB connection is in the same spot (I had to heat and bend the CB pipes about 1/8th on an inch). All depends on how different in spec the header/manifolds are. The rear bends will need to be fabricated to line up properly with the tailppe cutouts. Other than that, same hangers etc.

might you be interested in trading your Rs4 cat back for a set of Milltek S4 downpipes with 5k on them and I'll warranty the pipes. you can see pics of them in the classifieds.

The RS4 miltek catback is non res - valved. I'll need to get a few details and I will get back with you.

NO. it is not even close.

Seeing as they won't fit, can you just pick up the cat-back and work a deal with me?

Yeah RAudi, I'm waiting for the details from them. I haven't seen any pics yet so I don't know what type of condition there in either. I'll PM you when I get more info, I'm guessing it will be tomorrow.
