After Cat Flange
Friday, July 23, 2010 5:29 PM
Okay, I bought a cat-back from smoosh (thanks buddy), but it's missing the flange for the pipe right after the cat where the cat-back piping begins. I was thinking a universal 2.5" 3 hole flange would work fine.

Heres one I found:
http://www.mandrel-bends.com/catalog/flanges-v-bands-36/universal-exhaust-flanges-52/2-50-mild-steel-3-bolt-universal-exhaust-flange-639.html

Will this work? Do I need a new donut gasket too? A 2.5" gasket or an OEM replacement gasket? Or do I need an OEM pipe size flange as well? I feel like a newb asking this, but it's been so long since I've done any exhaust work that wasn't just cutting off a muffler....
