Borla XR-1 Racing Bullet Multi-Core Muffler 2.5" Center Inlet / 2.5" Center Outlet (40641)
Unleash uncompromised track performance and maximize horsepower with the Borla XR-1 Racing Bullet Multi-Core Muffler. Specifically engineered for extreme high-horsepower track configurations, street/strip builds, and compact custom spaces, this ultra-compact round bullet muffler features Borla's patented multi-core three-tube internal design. This innovative technology is fluid-dynamically proven to flow even better than a standard length of straight exhaust tubing. By completely eliminating restrictive backpressure, it drastically improves exhaust gas velocity to maximize horsepower and torque delivery, making it an exceptional choice for everything from high-RPM domestic race engines to punishing rotary track setups.
Built to endure the intense heat and harsh environments of competitive motorsport, this heavy-duty race muffler features a 100% welded chassis manufactured from premium T-304 stainless steel for lifetime protection against rust and corrosion. The compact round body features an inlet neck on one end with a flush, neckless outlet design on the other, making it perfect for dump styles, tight clearances, or welding directly to a custom tailpipe or turn-down. Sound attenuation is managed by premium, high-temperature T-304 stainless steel wool packing material, which dampens high-frequency harshness while preserving an aggressive, wide-open racing roar under acceleration. Delivering ultimate packaging flexibility with a fully reversible inline layout and a smooth, unembossed outer shell, this American-made unit arrives ready for custom weld-in fabrication.
