Stnd cat size

[Wrath]

Hey guys.

just a quick Q. does anyone know the size of the flanges on the stnd R33 gtst cat

i have heard talk of it being 3" but i dont think so.

ive just got a custom 3" cat back exhaust and im looking around for a dump+front pipe......

i saw one on ebay (flying 3" frontdump pipe) it says it bolts onto the stnd cat

but if the flange on the front pipe is less than 3" i dont want it :throwup:

The stock flange size works for 3" as well as the standard 2.5" piping.

it will be fine.

besides if you are worried that the front pipe will have a smaller flange because that is the only way to fit the std cat, then that would mean your cat back would need a smaller flange also to fit the std cat. so if the flanges were a problem then you would have to fix your cat back first anyway.
