Fabspeed's Valvetronic Maxflo Exhaust System is the ultimate catback setup for your C8 Corvette.

POWER:

The factory NPP (Valved) exhaust on the C8 Corvette flows pretty well with the valves open. However, with the valves closed it chokes the exhaust flow. Comparing the NPP exhaust with valves open to our Valvetronic Maxflo Exhaust with valves open, we saw peak gains of 4 whp and 6 ft/lbs of TQ. Comparing the two in valves closed mode, measured at the wheels we saw peak gains of 11.5 hp and 10ft/lbs of TQ, and curve gains as much as 14 hp and 15 ft/lbs of TQ. So whether you're in the comfortable valves closed mode or ripping around valves open, our Valvetronic Maxflo Exhaust System flows well and makes great power. We expect to see even more gains when compared to a C8 equipped with the base (non-valved) exhaust.

NOTES:

• On all Chevrolet Corvette C8 models, the Active Fuel Management (AFM) and NPP (if equipped) exhaust valves may need to be recalibrated after exhaust installation should the Check Engine Light (CEL) appear after the installation. GM dealers can reference GM document 5406413, or the re-calibration procedure can also be completed using a professional scan tool with this capability

SOUND:

We designed this system to have a two completely enthralling personalities, interchangeable as you see fit with the click of a button. You decide when you want to an aggressive sound with power gains you can feel laying on the throttle, or close the valves for a restrained sound when cruising through the city or neighborhood. Fabspeed's X-Pipe design gives it a hint of exotic mid-engine tone while bringing out the loping of the American V8. Check out our videos below to hear for yourself.
