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 oval racing muffler is the gold standard for performance exhaust systems. Specifically engineered for high-revving rotary engines and high-horsepower applications, this muffler utilizes Borla’s patented Multi-Core technology to deliver maximum exhaust flow without the restriction of traditional baffles. Its compact 16-inch oval design makes it the perfect solution for tight under-chassis spaces where performance cannot be compromised.
This muffler is not just about power; it is about longevity. The T-304 stainless steel construction ensures that your exhaust system remains pristine, even under the harshest racing conditions. The CRF acoustic material effectively manages exhaust notes, providing a deep, aggressive tone that is synonymous with the Borla name. Whether you are hitting the track or building a custom street machine, the XR-1 provides the flow characteristics needed to unlock your engine's full potential. Proudly made in the USA, this component is a staple for serious builders. Upgrade your exhaust performance with premium parts from GGCRACING.
