Product Description

The Borla 40947 XR-1 Racing Sportsman Muffler is a universal, high-performance exhaust component engineered for racing and custom performance builds. Featuring a straight-through internal design, it delivers maximum exhaust flow, helping reduce backpressure and support improved horsepower and torque output.

Built from premium stainless steel, this muffler is designed for durability under extreme performance conditions. Its 3-inch inlet and outlet sizing make it suitable for a wide range of high-flow exhaust systems. The center/center configuration allows for flexible installation, but due to its universal nature, professional fabrication or welding is required to ensure proper fitment.

This muffler is intended for motorsports and high-performance applications where unrestricted exhaust flow and aggressive sound are desired. As a universal component, it does not fit any specific year, make, or model without custom modification. Fitment is universal and installation will vary depending on the vehicle and exhaust setup.
