HKS HiPower Exhaust
HKS has used my car to prototype their upcoming HiPower exhaust for the G35 Sedan. It is an axle back design, so its very quiet. EDIT: The stock noise level is measured at 83db. With the exhaust, the noise level is measured at 87.3db. Way below the 95db noise limit here in California, so no need to worry about the cops harrassing you. The fitment is near perfect as you can see from the pictures.
Bone stock baseline dyno was 255.2 and the dyno after the exhaust was installed was 260.3hp (same day, same conditions). I was actually surprised by the 5hp peak gain for only adding an axle back system.
