Description

XR-1(r) Multi-Core Racing Muffler. 3" Center Inlet/ 3" Center Outlet 5.5" x 8.5" Oval x 34" Long Body 39.25" Overall Length. Designed for Pre-Runner trucks. Long body design works well on SUVs & trucks but can be used on a wide range of other vehicles including rotary engine equipped vehicles. Body has reinforcing ribs. It features BORLA(r)'S patented Multi-Core 4 tube design for maximum flow, horsepower, and torque. The Multi-Core portion of XR-1(r) 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 T-304 stainless steel wool packing for sound control. There is no BORLA(r) 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.
