Technology for performance exhausts

Technology for performance exhausts:

"Our engineers originally developed products specially adapted to increase power and torque for racing. Today we have adapted this performance exhaust technology for many more applications, in fact everywhere an internal combustion engine is used. There is no exhaust system that can matches the performance of the Vortex Exhaust. For an engine with 120bhp the Vortex can add between 12bhp and 20bhp, increasing your engine's efficiency by 10% plus. The Vortex Exhaust will give that gain even with a catalytic converter left in place"
