hi guys!

might be a silly question, but what is the best size cat to get for a standard exhaust?

IN/OUT PART#
1.75"

91003
2"

91004
2.25"

91005
2.50"

I'm guessing 2.25? But I thought id ask everyone. I currently have a mugen twin loop (dont laugh :P) and no cat. Just tryingt o make it legal :)

cheers in advance!

Stock cat size in and out is 2.5" in think. Someone please confirm.
Do you still have the stock piping? I use this one.

... It's so cool ! ...
I've put a 2.5inch in mine...to be honest 2.25-2.5 if you can get in that size will be fine. Make sure its a metal cat though. Try Magnaflow.

Did not know you paid already. Not sure if he ships overseas.
I paid $16.00 for Shipping to my US Mailbox, then they forwarded it to me in St. Kitts. If shipping is too high ask him to cancell becasue of shipping price and try one of these on ebay.com.au (I'm guessing that you are in Australia) http://cars.shop.ebay.com.au/Cars-Bikes-Boats-/9800/i.html?_nkw=universal+cat&_catref=1&_fln=1&_trksid=p3286.c0.m282
