The easy, effective way to quiet your race car.

The Vortex Insert Cone, installed near the exit of the header collector or muffler outlet, provides a large friction area to reflect and dissipate sound energy, thus reducing the dB level. Because no significant backpressure has been introduced, the engine is still able to use the scavenge ability of a good header to create horsepower and torque. Dyno and track testing show significant noise reduction with little or no power loss. Sold individually.
