Borla XR-1 Racing Sportsman 3.5 inch Center-Center 15in x 5in Round Muffler

This is the Borla XR-1 Racing Sportsman 3.5 inch Center-Center Round Muffler, part number 40086. It's a universal muffler designed for applications where space is tight, like door cars and roadsters. The XR-1 line is known for its race-winning technology, offering a solid balance between sound control and improved performance without sacrificing power.

Built from high-quality T-304 austenitic stainless steel, this muffler is made to last and won't rust. Its 100% welded construction ensures strength, and the free-flow design helps with exhaust gas efficiency. Inside, continuous-filament fiber acoustic material works to manage sound. The compact 5-inch diameter and 15-inch body length make it a great fit for custom exhaust builds where space is limited. Plus, its reversible design gives you flexibility during installation.

This muffler is designed for weld-in installation, and the un-notched necks are specifically made for this purpose. While it's built for performance, it also aims to provide a quieter driver compartment compared to many straight-through designs.
