Borla XR-1 Raceline Multi-Core Racing Muffler 2.5" Center Inlet / Center Outlet (401384)
Unleash maximum track performance and unlock hidden horsepower with the Borla XR-1 Raceline Multi-Core Racing Muffler. Engineered explicitly for high-horsepower race applications, custom street machines, and classic street rods, this ultra-compact 4-inch round muffler features Borla's patented Multi-Core 3-tube internal design. This race-winning configuration is proven to flow better than a standard piece of straight tubing, ensuring your high-performance engine breathes completely unrestricted. Frequently chosen as a premier "Hot Rod" muffler, it delivers a raw, aggressive exhaust note under heavy acceleration while using continuous-filament fiber acoustic packing to handle harsh tones without hurting power output.
Built to handle the extreme heat and brutal vibrations of competitive racing, this universal muffler features a 100% welded chassis made from premium T-304 stainless steel. The highly compact 12-inch body length makes it the perfect upgrading solution for custom builders dealing with strict underbody clearance constraints or tight packaging layouts. Its fully reversible design provides fabrication flexibility, allowing it to be integrated easily into a wide range of custom exhaust systems. Arriving in a classic natural mill finish that can be brushed or polished prior to installation, this American-made race component delivers the ultimate in durability and exhaust scavenging.
