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.
When space is at a premium but performance is non-negotiable, the Borla XR-1 Multi-Core 3-inch oval muffler (12-inch body) is the ultimate choice. Designed for high-horsepower engines, including rotary configurations, this muffler packs the same patented Multi-Core technology as its larger counterparts into a compact 12-inch frame. It is the perfect solution for vehicles with limited clearance that still require an unrestricted, high-flow exhaust path to reach peak performance.
Every Borla XR-1 muffler is constructed with 100% welded seams, ensuring it can withstand the extreme thermal cycling of racing environments. The use of high-temperature continuous-filament fiber (CRF) ensures that the sound remains controlled and deep, avoiding the harsh rasp often found in lesser racing mufflers. Because there is no logo embossment, it offers a clean, professional look that integrates seamlessly into any custom exhaust build. Whether you are optimizing a drift car, a drag racer, or a high-performance street build, this muffler delivers the reliability and power you expect from the world’s leading exhaust brand.
