Choose options
Unlock the best of both worlds with Fabspeed’s Valvetronic Maxflo Exhaust System for your 2020+ C8 Corvette. Retain the factory NPP (valved) functionality but upgrade to a system that breathes better, saves weight, and offers two distinct sound profiles—refined cruising or aggressive, high-output V8 roar—all at the touch of a button.
Sound & Drive Modes

Aggressive Open-Valve Mode
Experience a rowdy exhaust note reminiscent of classic muscle, topped with an exotic mid-engine twist, courtesy of the X-pipe design. -
Restrained Closed-Valve Mode
Quiet down for neighborhood or highway driving without sacrificing power gains—virtually drone-free and refined for daily use.
