Borla Performance Industries was founded in 1978 and remains America's premium cat-back exhaust brand. Every Borla system is hand-built from T-304 austenitic stainless steel and backed by a million-mile warranty — the OE choice for Camaro ZL1, Mustang GT350, and Chevy Corvette.
The Borla XR-1 Multi-Core 3-inch round racing muffler is engineered for those who need a long-body solution for high-horsepower applications, such as performance trucks or dedicated race vehicles. With a 16-inch body length, this muffler provides the internal volume necessary to effectively manage exhaust gases while maintaining a straight-through, unrestricted flow path. It is designed to deliver the raw power and aggressive sound that Borla is famous for, all while maintaining the durability required for competitive racing.
Built to last, this muffler features 100% welded construction that prevents leaks and structural failure under intense pressure. The round profile allows for easier fitment in many chassis designs compared to oval alternatives, making it a versatile choice for custom exhaust fabricators. By utilizing high-temperature continuous-filament fiber (CFF), the muffler effectively reduces harsh frequencies while allowing the engine to breathe freely. This is the perfect upgrade for any builder looking to combine the reliability of American-made quality with the performance of a winning exhaust brand. Find your next exhaust upgrade at GGCRACING.
