Borla XR-1 Racing Sportsman 3 inch Outlet / 3 inch Inlet Round Muffler

If you're building a compact race car or a roadster and need a muffler that won't take up a lot of space, this Borla XR-1 Racing Sportsman round muffler is a solid option. It's designed to fit into tight spots where larger mufflers just won't work, giving you the flexibility to get your exhaust system routed just right.

This muffler uses Borla's patented, race-winning XR-1 technology, which means it's built for free flow and improved performance without sacrificing too much sound control. It's made from high-quality T-304 austenitic stainless steel, so you know it's going to hold up and won't rust, even in harsh conditions. The 100% welded construction adds to its strength, and the internal high-temperature continuous-filament fiber acoustic material helps manage the sound. Because it's a universal part, it's reversible, which can make installation a bit easier depending on your setup.

This muffler is designed for welding in, but if you prefer to use a clamp, a 3-inch wide band clamp is recommended. The natural mill finish means you can polish or brush it to match your build before you install it.
