FABSPEED C8 Corvette Valvetronic Maxflo Exhaust System


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


    We designed this system to have a split personality. It's loud and aggressive when you want it; civilized and restrained when you need it. It really brings out the American V8 sound, however, the X-Pipe design gives it a hint of exotic mid-engined tone. Check out the video below to hear for yourself!


    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 the Valvetronic Maxflo Exhaust with valves open, peak gains of 4 whp and 6 ft/lbs of TQ. Comparing the two in valves closed mode, measured at the wheels with peak gains of 11.5 hp and 10ft/lbs of TQ, and curve gains as much as 14 hp and 15 ft/lbs of TQSo whether you're in the comfortable valves closed mode or ripping around valves open, the Valvetronic Maxflo Exhaust System flows well and makes great power.
