My exhaust: ARK Grip 2.5" pipes.

Theory: Smaller exhaust diameters are usually beneficial to midrange performance, at the expense of top end.

Real world: I have INCREDIBLE midrange power and it's helping my performance at the track (drag strip), or simply not hurting it.

I'm proof positive you do NOT have to go for a 3" diameter exhaust to get results. In fact, there may be something in my recipe that bears understanding.

You may theorize all day long, but I have a completely full weight heavy G37 and it has proven itself with smaller 2.5" pipes. Anomaly or formula?
