Again, prove me wrong. I've done the math and understand things like torque multiplication and ideal shift point calculations. Additionally, I have tested 3.55s are the strip with my 5AT. From a driveability standpoint, the additional torque multiplication will feel nice to the old butt dyno, but our cars don't come from the factory with poor gearing. This isn't a 96-98 Cobra with tall 3.27 gears which makes decent gains (.3 seconds) when going with 4.1-4.3 gear sets.
I've seen guys gears who have shave .2 sec from the 3.5 to the 3.9 and 4.08.

I used to have the HR y-pipe, cpe MP, and HKS muffler. I gained 10 WHP at PEAK with the Motordyne over this exhaust. The area under the curve was better than that.
