I have a 96 firebird, just recently got it and it is still stock. Can anyone tell me what the stock size exhaust coming from the manifolds is? I am looking to get a high flow cat and slp loudmouth exhaust, just needing to know what size to match up to and what size will help me the most.

The stock cat is 3" In / 2.25" Out, and the I-Pipe is 2.25".
BTW, it's very easy to find this in a search.Matt
