Thomas C came in for full 60k mile services and a new exhaust system on his G37 S sedan.

The old exhaust system had an aftermarket y-pipe that didn’t significantly increase power. We installed a full cat-back system from Fast Intentions followed by an UPREV tune. Old vs new:

The new exhaust looks and sounds great:

On the dyno we were impressed with gains from the FI exhaust combined with UPREV tuning. Peak numbers were 302hp/249tq to the wheels, an increase of +15hp/10tq. Check out the mid-range tp redline gains in both hp and tq from 3500rpm:
