This is an exciting new product; however, it should be noted that it will NOT change the sound of an NPP equipt Camaro at idle. The dual Mode exhaust is already open at idle. This will primarily change the sound between 1000 and 3500 RPMs when the valve is usually closed (unless throttle is > 25%; I believe).
Still, I will put this on my list of upgrades to consider.
CAI Intake w/washer relocation and race scoop
Ported Throttle Body (Polished)
Kooks LT stepped headers 1-3/4 to 1-7/8
High Flow Cats
Livernois Motorsports Stage 2c Cam Package
Soon: New Tires...
