is there any difference in piping size for the vrx over regular 3.5l
just wanting to know if im able to use a th cat on the vrx??

Hey Adam :P

I believe the cat is the same. The only difference between the vrx and the standard is the rear muffler section was changed over to a straight through. Further work was done on the ralliarts which saw a new center muffler installed to help with droning, as well as the extractors installed etc.

yo josh long time lol

cool just the answer i was after

hmmmm not too long ago i had to replace my cat, the bloke said i needed a more high flow cat as its a VRX and the standard ones are a lil bigger??
