High-performance muffler with uninterrupted flow design for maximum power.

The Borla XR-1 Series Exhaust Muffler is engineered for high-performance applications, featuring a patented uninterrupted-flow design that enhances exhaust flow efficiency. Constructed from premium T-304 stainless steel, this muffler ensures durability and longevity, making it suitable for both street and track use.
