I have a 2.5 inch dynomax catback.Other than that,the exhaust is stock.Which size cat do I need?? Would 2.5in/out work? Do I need air tube or no air tube? The car is a 91 3.1 v6 firebird.

good luck with someone to answer this question I do believe it is 2.5in in and out but i'm not exactly sure. I asked this question before and now answer and I searched and it's never answer in there. well atleast with what i could find.
Air tube you will need it unless you plan to swap your manifolds for headers around the same time. If you do you can take the entire airpump off95 camaro 3.4 < Jc whitney Exhaust, Chrome intake stage 2, Rk sport headers, msd dis-4, 160*thermo, Jet stage 2 chip, black racing stripes.<br /><br />91 Camaro rs 5.0 tbi gone but not forgoten
