Borla XR-1 Sportsman Racing Muffler 4in In/4in Out Muffler

This Borla XR-1 Sportsman racing muffler is built from high-quality T-304 austenitic stainless steel, which means it won't rust and offers solid strength with its 100% welded construction. It uses Borla's patented, race-winning XR-1 Raceline technology, which is a free-flow design intended to improve performance without sacrificing too much driver comfort. The muffler is packed with a high-temperature continuous-filament fiber acoustic material to help manage sound levels, aiming for a good balance between a powerful exhaust note and a quieter cabin.

This particular model features a 4-inch center inlet and a 4-inch center outlet, with an oval body measuring 4.25 inches by 7.88 inches and a 16-inch body length for an overall length of 21 inches. Its reversible design offers flexibility during installation, making it easier to route exhaust systems in tight spaces, especially in door car or roadster applications where compact size is crucial. The natural mill finish allows for custom brushing or polishing before installation.
