Anybody know where I can get the RS-R Exmag catback at the lowest price?? I've seen the full stainless steel one for $549, which I think is retail price.
Also, whats the difference between the USDM and JDM ITR mufler?

 

I don't think theres any difference in the mufflers for Type R's, but don't quote me. As for the Ex-mag, thats probably the lowest price I've seen for that exhaust.

 

hmmmmm so then its just the piping to the muffler?

 

I'm not quite getting what you mean by this, but I ment cat-back.

 

I ment the only thing larger in diameter between the two is the bpipe?

 

I don't even think the B-pipes are different. To my knowledge, they were all 2.36" diameter.

 

i thought the usdm was 2.25?? hmmm Idk... but im pretty sure theres something different between the two exhausts.

 

Thats why I said not to quote me, that just what I've read. Sorry I can't give you a concrete answer

 

RSR cutoff all their dealers and decided to go retail direct themselves. Their pricing MSRP is probably the best price you can get. Dealers that are still with them selling lower are making little or no money at all.

Piping on the exhaust should be the standard 60mm. (~2.46 inches) which is close to 2.5 inches. Your factory diameter is about 2-2.25.

 

60mm is 2.36".

Stock GSR/ITR is 2".
