Description
XR-1® Multi-Core Racing Muffler. 3" Center Inlet/ 3" Center Outlet 4.25" x 7.88" Oval x 12" Long Body 17" Overall Length. Compact size is perfect for applications with limited space and can be used on a wide range of vehicles. It features BORLA®'S patented Multi-Core 4 tube design for maximum flow, horsepower, and torque. The Multi-Core portion of XR-1® mufflers flows better than straight tubing. Recommend for high horsepower applications. Reversible design for installation flexibility. T-304 Stainless steel for superior corrosion resistance. Natural mill finish can be brushed or polished prior to installation. 100% welded construction for strength. High-temperature continuous-filament fiber (CRF) acoustic material for sound control. There is no BORLA® logo embossment on this part. Best of all, it's made in the USA. Just what you’d expect from the world’s most experienced (and most winning) exhaust brand.
