Racing Exhaust Products


Torque-Cones are a simple product that reduce the turbulence and increase the velocity of the gasses leaving the exhaust system. This improves the scavenging ability of the header, which increases cylinder fill and increases both horsepower and torque in any racing engine.

Torque-Cones are the result of many years of careful research on the dyno and on the track. The size of each Torque-Cone is selected to optimize the flow of the header for which it is intended to be used on. This provides a reduction of noise, and an increase in horsepower and torque over the entire RPM range.

Torque-Cones will make your engine behave more like an engine that has been fitted with an expensive merge or tri-y exhaust system for a fraction of the cost.


If you’re looking for an edge over the competition next season, Torque-Cones will surely give you one!
