Borla XR-1 Racing Sportsman 3 inch Outlet / 3 inch Inlet Round, Oval or Offset Muffler

Built from high-quality T-304 austenitic stainless steel, this Borla XR-1 Racing Sportsman muffler is designed for performance applications where exhaust flow and a controlled sound are critical. The patented, race-winning XR-1 technology uses a free-flow design with internal acoustic material to manage sound without sacrificing power. This makes it a popular choice for racers and performance enthusiasts looking for a balance between a quieter driver compartment and maximum engine output.

You have a few options with this universal muffler. The oval version is Borla's best-selling racing muffler, known for being lightweight and compact while offering high flow. The round option is specifically designed for door car or roadster applications where space is limited, measuring 5 inches in diameter and 15 inches long. There's also an offset inlet/outlet version designed to help clear transmission or frame rail interference on certain vehicles. All versions are 100% welded for strength and feature a reversible design for easier installation flexibility. The natural mill finish can be polished or brushed before installation.
