Overall how do you like how the car drives now? I'm sure it feels alot better with the nice gain that carries though 3000-4000rpm...

Before headers 3000rpm:
131 hp
230 ft/lbs

After headers 3000rpm:
140 hp
245 ft/lbs

Thanks again for posting.

Does a 5% increase in torque really make much difference? Can you feel it?

Im interested in its gains as well. I have an intake, headers, 1 pair of high flow cats, custom SS front pipe, 3rd cat deleted to X pipe going into a Blitz muffler. Sounds raw. Im sure I can use more fuel somewhere in the RPM band.
