Hey guys I have a 2000 Si, and I was wondering if a high flow cat from a 92 with a B18C swap in it.

I am needing a cat that is 2.5 inlet and outlet, ordered one that claimed it was a 2.5, got it intoday and its a 2.25.

Any help is appreciated.

Thanks
Michelle

Returned what you ordered, get another one with the right inlet and outlets or get your money back. Simple, as far as the high flo CAT goes, without a brand or model number were in the dark. GL

all USDM exhausts are made to accept a 2.25 inch flanged exhaust components. without modifying anything, the cat should fit. if you want to spend more time and get a larger header and cat-back then its worth it to go 2.5. Its a waste to go 2.5 with other stock, or small sized exhaust components. PM ME if you need more help on this. i just went through exhaust flange hell with a 2.5 cat and JDM header thing.

Yeah well I have a header that is a type r, and it doesn't bolt up to my high flow cat that is 2.25.
I have the cat back exhaust, but I went ahead and got this race cat that is 2.5 to match up to the header.
Cause I was thinking, first how stupid was I, but the year of the car doesnt matter cause its a different engine in there.

Thanks for the help though guys. I did contact the guy I bought the cat from, the wrong one and he told me to pay for the shipping back and then he will refund my money. If I don't pay to ship it back I get no refund. So I'll just post it up for sale or whatever with it =)
