It typically includes the muffler and exhaust pipes that extend from the rear axle to the back of the vehicle. Axle back exhaust systems are designed to improve the sound and performance of a vehicle by increasing exhaust flow and reducing restrictions. They are relatively easy to install and do not require any modifications to the vehicle's exhaust system before the rear axle. Axle back exhaust systems are a popular choice among car enthusiasts who want to enhance the sound and appearance of their vehicles without modifying the entire exhaust system. Professional Installation Is Highly Recommended!
