Hi everyone!

We just completed some dyno pulls on our project G35 Coupe 6-spd.

First run - Completely Stock

Second run - Helix cat-deletes, Helix prototype cat-back exhaust (w/Y-pipe).

Dynojet Dyno. Temperature from 67 degrees to 74 degrees final run (due to facility heating).

Based on the dyno, we were quite pleased. Especially since on the 4th pull (not shown, the car actually peaked at 248whp) . FYI a 350Z with Nismo headers, cat-deletes, exhaust system made 247whp a few weeks ago and when we plotted the graphs together it actually made lower torque numbers in the midrange.
