Performance exhausts are aftermarket systems designed to improve a vehicle's exhaust flow, enhancing engine efficiency and power output. By reducing back pressure, these exhausts allow for better airflow, which can lead to increased horsepower and torque. They are often made from high-quality materials like stainless steel to resist corrosion and provide durability. In addition to performance benefits, performance exhausts can also change the sound of a vehicle, giving it a more aggressive tone. Many enthusiasts choose these systems not only for the added power but also for the enhanced auditory experience, making their vehicles stand out on the road.
