XR-1®

BORLA's XR-1® raceline products are the choice of today's hottest racers. Featuring a patented uninterrupted-flow design and multi-core technology, BORLA's XR-1® mufflers actually outflow a straight piece of pipe. XR-1® race products are made in the USA and constructed of high-quality T-304 stainless steel for track tough durability. They meet the strictest noise requirements. Multi-Core, Collector, and Bullet Racing mufflers feature steel wool packing for sound control. Sportsman mufflers feature high temperature continuous filament fiber (CFF) for sound control. Hands down, BORLA’s XR-1® raceline parts offer the best balance of sound and power.

  • T-304 stainless steel will never rust — our thickest material.
  • Free-flow design for improved performance.
  • 100% welded construction is track-tough.
  • Multicore, Collector, and Bullet Racing muffler feature steel wool packing for sound control.
  • XR-1's race-proven design attenuates sound without restricting flow.
  • Sportsman mufflers feature high temperature continuous strand fiberglass (CSF) for sound control.
  • Natural mill finish can be brushed or polished.
  • Reversible design for installation flexibility.
  • Recommended for high-horsepower racing applications.
