The Borla XR-1 Multi-Core Racing Muffler (MPN: 401384) is engineered for high-horsepower applications where maximum exhaust flow and space efficiency are critical. Featuring Borla's patented Multi-Core three-tube internal design, this muffler is proven to flow better than a straight piece of tubing while providing essential sound attenuation for track or high-performance street use.

Constructed from premium T-304 stainless steel with 100% welded seams, this 4-inch round muffler is designed to withstand extreme temperatures and resist corrosion. Its compact footprint makes it an ideal solution for custom builds or any vehicle with limited underbody clearance. The natural mill finish offers a clean look out of the box and can be brushed or polished to match your build's requirements. High-temperature continuous-filament fiber (CRF) acoustic material ensures long-lasting sound control without degrading over time.
