Sportman XR-1 Muffler 2-1/2 in/out

The BORLA Sportsman XR-1 Muffler 2-1/2 in/out (SKU: BOR40942) is a universal stainless steel exhaust component engineered for automotive enthusiasts seeking a balance between performance and everyday driveability. This 2.5-inch center inlet and outlet muffler is built for mechanics and vehicle modifiers who understand that proper exhaust tuning improves throttle response, fuel efficiency, and engine longevity. Whether you're refining a street machine, daily driver, or weekend project, the XR-1's oval body design integrates into most custom exhaust systems without requiring extensive fabrication.

BORLA's XR-1 Sportsman muffler uses stainless steel construction to resist corrosion and heat degradation over extended service life. The 20-inch length and 16 x 4.5 x 7.875-inch oval body profile reduce backpressure while maintaining acoustic characteristics suitable for street use—avoiding both drone and excessive noise that invite unwanted attention. The dual 2.5-inch smooth flow passages minimize turbulence, allowing exhaust gases to exit efficiently without restrictions that rob horsepower or create heat soak near engine bays. Weighing 8.71 lbs, it's light enough for weight-conscious builds yet rigid enough to withstand thermal cycling and vibration without rattling or premature failure.

This universal muffler fits most custom and OEM-derived exhaust systems with 2.5-inch tubing, making it ideal for hot rodders, truck builders, and import tuners developing personalized exhaust flow paths. Installation requires standard clamp or welding techniques; center inlet and outlet positioning allows flexible piping geometry from header to rear axle. Natural stainless finish resists weathering and blends seamlessly with polished or ceramic-coated exhaust components. For any builder prioritizing balanced performance, longevity, and craftsmanship over off-the-shelf solutions, the BORLA Sportsman XR-1 delivers the foundation for a refined exhaust system that performs as intended.
