Borla XR-1 Multi-Core 3in Center/Center Round Racing Muffler 16in x 6.25in (400373) - Rotary Engine Equipped
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The Borla XR-1 Multi-Core Racing Muffler (400373) is engineered for high-horsepower builds and specifically optimized for rotary engine applications. Featuring Borla's patented 4-tube Multi-Core internal design, this muffler provides exhaust flow that actually exceeds a straight pipe of the same diameter, ensuring maximum horsepower and torque gains without the flow restrictions of traditional baffles.
Constructed from 100% welded T-304 stainless steel with a natural mill finish, the XR-1 is built to withstand extreme track conditions. High-temperature continuous-filament fiber (CFF) acoustic material provides long-lasting sound control and thermal stability. Its reversible, center-to-center configuration allows for versatile installation across a wide range of platforms, from racing sedans to high-output trucks and SUVs.
