it should be more than 300. if i remember they were rated at 275 from factory, yet i think everyone knows they're underrated. i'm thinking like 320-3401994 Firebird Formula
CRT Intake Elbow
New speakers in doors - one 10' in back
Trans Am hatch
C5 Rims F17x8.5 R18x9.5
I figure I'm at 300 at the flywheel? Expecting full exhaust soon. Longtubes, y-pipe and pipes out the back.
