question about exhaust and cat....
my cat is junk. just no good at all. Its cloggd and the bolt holes that hold the heat shield on have rotted out into 1/2" big rot holes. Just got a new as shyt OEM cat back exhaust from the j-yard for $7. It was a 9 out of 10. seriously...nice as hell for a stock exhaust. So i was lookin at gettin a replacment....$100. No. Then i looked at some ebay test pipes and was told that most test pipes are 3" and wont work with my exhaust. So then i hit up ebvay again and put in 1991 240SX catalytic converter. It brought up a couple Hi-Flow cats. Will these work at all?? Dont have $100 to drop on a new cat. Hi-Flo cat was only $30(w/ shipping included). Any help with this will be greatly appriciated. Thanx fellas

the piping maybe a different but the flanges are the same size, if you are a strict observer of the principles of exhaust theory you'll get a cat with the same inner diameter of the rest of your exhaust to avoid turbulence. most people don't know or care about that though and just go with what's bigger becuase in their mind bigger is always better.
