i just switched from a h/c 04 gto to the new 2012 mustang gt... im about to do some bolt ons and was wondering which ones to go with ive heard the boss 302 intake kills torque on the lower rpms? im probably gonna go x pipe(catless)steeda cai, and slp axle back.. what kind of gains do these new mustangs get with headers? oh ya i been pondering on the 3.73 gear mine has the 3.31..
