Borla XR-1 Raceline Sportsman Racing Muffler 2.5" Center Inlet / Center Outlet (401392)
Strike the perfect balance between track performance and acoustic control with the Borla XR-1 Raceline Sportsman Racing Muffler. Engineered specifically for high-horsepower race applications and custom street builds, this universal round muffler features a premium straight-through, free-flow internal layout. This high-flowing configuration eliminates backpressure to maximize exhaust scavenging, horsepower, and torque. It delivers a raw, competitive exhaust note under acceleration, while using advanced continuous-filament fiber acoustic packing material to filter out harsh frequencies without robbing your machine of power.
Built to endure the brutal heat and vibrations of competitive track use, this heavy-duty muffler features a 100% welded chassis crafted from premium T-304 austenitic stainless steel for ultimate corrosion resistance. The smooth, un-notched necks are specifically optimized for a clean weld-in installation by custom fabricators, though it can also be secured using heavy-duty wide two-bolt style band clamps. Its compact 5-inch round body profile fits easily into tight underbody spaces, and the fully reversible design allows for total fabrication flexibility. Made in the USA, this race-proven unit is the ultimate performance upgrade for your custom exhaust project.
