Hey guys,

So I've just ordered RPWs Header/Downpipe and Bolt on High Flow Cat and I was wondering, if RRMs Catback exhaust would bolt up/match with RPWs Header/Downpipe?

Does anyone have pics of their exhaust pipe? Anyone?

Cheers

 

i was wondering that to.

 

Probably when I recieve the header/downpipe, I'll measure the downpipe measurements and ask ROCK if he could see if they match..

 

If the RPW header/downpipe is made to bolt up to the the stock exhaust and the RRM catback is made to bolt up with the stock downpipe they should bolt up. Unless there's something differen't about them i don't know about.

As long as RPW has made the 4" addon for USDM RA's then it should bolt up fine.

 

^^never heard about this. i guess you needed to weld in an extra piece of pipe on yours then? wonder why our cars and theirs have a 4" difference like that anyway.

 

you can see the add on piece AdamRA is talking about in these pics https://www.evolutionm.net/forums/sh...d.php?t=218099 the catback portion of that exhaust seems to be modified...
your best off calling rpw to see if their setup will bolt up to the stock USDM ralliart catback... if they say yes then obviously the rrm catback will work. if they say no, then you modify it and make it work.

It won't bolt up to the stock USDM Ralliart CB or RRM's CB without the 4" extension. Those pictures are of my car and my CB sits exactly where the stock CB sits. I believe RPW has made that extension but you would have to ask them to get a definite answer.

 

Its all good now, I've decided to go custom cat back..

Cheers
