SOUND: Fabspeed 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 lopey American V8 sound, however the X-Pipe design gives it a hint of exotic mid-engined tone. Check out their videos below to hear for yourself!
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, their 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.
