get a 3" cuz youre eventually gonna want to do more mods and youre gonna need a bigger downpipe/exhaust... unless you wanna spend the money twice.
just get 3"CAI/DP and Exhuast.
follow the saying... the bigger the better.

So many people do not understand exhaust gas flow on this website. You want flow, but you also want to maintain good exhaust gas velocity. Bigger pipe will slow the velocity down unless you are making big power. A 2.75"-3" downpipe to a 2.5" catback is more than enough for more than 75% of the Balts on this site.
Bad advice .... This is not always the case.
