The Borla XR?1?40085 Sportsman racing muffler is a versatile, high-flow weld-in unit designed for use with any 3? exhaust system. Whether you're upgrading a V6/V8 muscle car, truck, race build, or off-road rig, this muffler delivers aggressive performance while maintaining street-legal acoustics.

Built from T?304 austenitic stainless steel and 100% hand-welded in the USA, the XR-1 features high-temperature multi-core CFF acoustic packing and a brushed stainless exterior. Its compact, reversible 15? × 5? round body is ideal for tight clearances and offers flexible installation options.
