Bosal Performance - Select Import & Domestic Car and Truck Performance Exhaust Systems.           1. Escaping exhaust gas creates pressure wave moving down the system. 2. Wave hits the system’s end, causing “suction wave” to travel back up the system. 3. Suction wave hits the cylinder and reverses direction just as the exhaust valve opens. The suction wave helps pull exhaust gases from the cylinder improving engine breathing and volumetric efficiency. Bosal Performance - high performance exhaust with real gains in horsepower and torque. For performance compacts and trucks. While others talk performance, Bosal delivers with true, tuned exhaust systems that harness the power of the exhaust pulse wave.   Bosal Performance Mufflers - free-flow design with tuned expansion chambers for better torque + higher horsepower.
