Borla 3.5in Tubing x 6.25in Diameter x 24in Length Multi-Core Center/Center Round Racing Muffler

Borla is known worldwide as a leading exhaust manufacturer, with a long history of success in racing. This XR-1 Raceline muffler is a prime example of that expertise, built for vehicles competing in venues that require a muffler, but it's also a solid option for other applications. It features a patented uninterrupted-flow design and Multicore technology, which Borla states actually outflows a straight piece of pipe in testing. This design is recommended for high horsepower applications where maximizing power is key.

Constructed from high-quality T-304 austenitic stainless steel, this muffler is built for track-tough durability and will not rust. The 100% welded construction adds strength, and the high-temperature stainless steel wool packing helps control sound. The long body design, measuring 24 inches, works well on trucks, and its reversible nature offers installation flexibility. If you're looking for a well-built muffler that offers a great balance of sound and power for demanding use, this Borla XR-1 is a strong contender.
