Stock Y pipe to CAT adaptor
Quick question. I got my CATCO cat(9118) and my Hooker Cat-back(16823) today. I dont have money readily available to buy the 2055's that i want so i was gonna hook up the cat and cat back that i got right now. Whats the size of the stock y pipe. The in pipe on the cat is 3 inch so i need a XX to 3 inch adaptor. Thanks!

89 rs was only available with the L03, TBI 305.
I believe your Y-pipe is 2.25. Just grab a ruler and do some quick measuring.
