What size is the stock exhaust? 84 T/A 305 H.O. w/auto trans
Hey guys. I picked up a set of hooker 2055's with the 3" y-pipe however I'm still running the stock exhaust the rest of the way out so I need to pick up a reducer. I haven't been able to get an accurate measurement, but from what I"ve got, I'm thinking it's 2.5" stock. Is that right?

I went with the 2055's, a Catco 9118, and a Hooker catback. Everything was a direct fit, which appealed to me. The problem that you'll face is that your oval OEM Y-pipe will have a four-bolt flange as will your cat, so some modification will be required to mate the latter to the Hooker Y.
