Please select your tip finish prior to adding to cart.
The Valvetronic Maxflo Exhaust System is engineered for the C8 Corvette to improve exhaust flow while retaining factory valve functionality. The system maintains performance in both valve positions, offering increased output whether operating in open or closed mode.
Dyno testing compared to the factory NPP (valved) exhaust showed gains of approximately +4 wheel horsepower and +6 lb-ft of torque with the valves open. In closed-valve mode, testing recorded peak gains of +11.5 wheel horsepower and +10 lb-ft of torque, with curve gains reaching up to +14 horsepower and +15 lb-ft at the wheels. Additional improvements may be realized when compared to vehicles equipped with the base non-valved exhaust system.
