I would say get the same diameter as your exhaust system to eliminate a bottleneck.. So that would probably be 3".. But if you don't have headers or plan on getting them, then you might not see a difference between 2.25, 2.5, or 3".. I'm not sure of all the different flow rates, but if anyone knows them from the exhaust manifolds, just make sure you keep a flow rate above that to prevent a bottleneck.
You may also want to look into a CarSound converter, they supposedly are pretty good with not throwing any codes.. I got one put on and I am getting a code but I think it's from a faulty sensor in the headers.. The CarSound converter is relatively cheap too.1996 Camaro Z28 M6<br />Red, T-tops, 5.7L LT1<br />Borla Cat-Back, SLP PP/ClutchComment
