Exhaust Systems


 Performance Exhaust Systems

Performance exhaust systems are available in multiple sizes. The most common is a four-inch, these are designed for vehicles creating less then 450 horsepower. Larger diameter exhaust systems such as five-inch, are typically recommended for vehicles creating greater then 450 horsepower. Performance exhaust systems increase exhaust flow by eliminating the restrictive stock muffler, replacing factory crimped bends with smooth mandrel bent tubing, and increasing the overall pipe diameter. The benefits of increased exhaust-flow are reduced EGT's(exhaust gas temperature), increased horsepower/torque, fuel mileage gains, and a deep throaty sound.
