Dominate the track and unlock hidden horsepower with the Borla XR-1 Raceline Multi-Core Racing Muffler. Engineered specifically for high-horsepower race configurations, custom street machines, and classic street rods, this slim 4-inch round muffler features Borla's patented Multi-Core 3-tube internal design. This race-winning technology is proven to flow better than a standard piece of straight tubing, giving your performance engine completely unrestricted breathing room. Widely known as a premier "Hot Rod" muffler, it delivers a raw, aggressive exhaust note under heavy throttle while using premium acoustic fiber packing to control harsh frequencies without stealing a single pony.
Built to survive the extreme heat and harsh vibrations of competitive racing, this compact universal muffler features a 100% welded chassis crafted from premium T-304 stainless steel. The slim 4-inch diameter case makes it the ultimate upgrading solution for vehicles with tight underbody clearance or limited workspace. Its fully reversible design provides custom fabricators with maximum installation flexibility during system mock-up. Arriving in a classic natural mill finish that can be brushed or polished to perfection, this American-made race muffler comes backed by Borla's reputation as the most experienced exhaust brand in the industry.
