I know butt dynos lie, but ain't noooooo way my intake/full exhaust car is 320+whp lol. My catback 6.0 GTO made SAE 340-345whp on 3 back to back runs, and other than the violent 1st gear with 4.10's I have I still don't think it would pull on the GTO. Maybe it's the illusion from the power falling off over 6k rpm's, but I'm honestly a bit disappointed. I figure the only way to solve that without getting spending serious money is a ported intake/98 Cobra cams.
