Product Description

The Borla XR‑1 40085 Sportsman racing muffler is a versatile, weld-in unit designed for any 3″ exhaust build--ideal for muscle cars, trucks, racers, and off-road builds needing a compact, high-flow solution. With its straight-through core and multi-core CFF packing, it outflows straight pipe while offering a deep, clean tone with minimal cabin drone.

Built entirely from T‑304 stainless steel and hand-welded in the USA, this round muffler is reversible, space-conscious (15″×5″ body), and covered by Borla’s renowned Million-Mile Warranty. Drivers report it's sufficiently quiet for street and track, yet aggressive under WOT--making it a solid choice for those wanting flow-first performance without sacrificing refinement.
