Sportsman XR-1 Muffler 4in In/Out x 16in

The BORLA Sportsman XR-1 Muffler with 4-inch inlet and outlet is a stainless steel exhaust component engineered for vehicles requiring universal muffler fitment. This 16-inch long oval-body muffler delivers sound attenuation while maintaining structural integrity in demanding conditions. The center inlet and center outlet configuration accommodates a wide range of exhaust system layouts, making it a versatile choice for custom exhaust installations and restoration projects where OEM muffler replacement is necessary.

Built from stainless steel construction, the XR-1 resists corrosion from road salt, moisture, and heat cycling—critical for long-term durability in varied climates. The 4.5 x 7.875-inch oval body shape is engineered to fit within typical vehicle undercarriage clearance while providing efficient sound dampening chambers. The 20-inch total assembly length and precise 4-inch center connections ensure compatibility with standard aftermarket and custom exhaust piping. This muffler is finished in natural stainless, requiring no additional coating and remaining corrosion-resistant throughout its service life.

The Sportsman XR-1 serves enthusiasts and technicians performing full exhaust system builds, vehicle restorations, and custom installations where bolt-on universal mufflers offer simplicity over model-specific components. Its moderate 9.33-pound weight reduces system strain compared to heavier muffler designs. Technicians value BORLA's engineering for predictable fitment and sound quality when constructing exhaust systems from component parts rather than relying on integrated OEM assemblies.
