okay, that title is about as clear as mud. here is the deal, my car is a Canadian car and never had a cat, but I need one to get it though emmisions. they just have to see a cat, that is it. most cats attach to a flange, but is there a cat out there that is just 2 1/4" on either end and will slide over my 2" exhaust? any recommendations on where to get a dirt cheap cat in 2 days?
