I'm installing my Thorleys on my 3.0 and cant find the correct rear cat gasket. Autozone has one in stock but its just a donut not a 2 bolt flange gasket which is what I assume I need as that's whats in there now! I have a Borla catback with a magnaflow cat. Anyway does anyone have a fel-pro part number for the rear cat? I know when I put my MagnaFlow in I got the gaskets at Autozone front and rear and they were exactly what I needed not just a ring, though I may be able to use the ring gasket, Im just not sure how it would like my Borla. Any input would be great!

All my cat gaskets have been doughnuts on the OEM set-up.They work way better than flat gaskets, which is why Toyota uses them I suspect. -- Matt

I'm going to grab one of the donuts and see how it mates up to my Borla catback and Magnaflow cat, should be OK I just dont know if either of my parts are routed out for the donut type gasket, I think they are both flat flanges!
