Borla XR-1 Raceline Multi-Core Muffler 3" Center Inlet / 3" Center Outlet (40575)
Unleash uncompromised track performance and maximize horse power with the Borla XR-1 Raceline Multi-Core Muffler. Specifically engineered for high-horsepower racing applications, street/strip builds, and demanding engine setups where chassis space is tight, this compact oval 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 optimize horsepower and torque delivery, making it an exceptional choice for everything from high-RPM domestic race engines to punishing rotary configurations.
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. 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 installation flexibility with a fully reversible inline layout and smooth, un-notched necks, this American-made unit arrives in a classic natural mill finish that can be brushed or polished to a mirror shine prior to a custom weld-in fabrication.
