XR-1® Multi-Core Racing Muffler. 3' Center Inlet/ 3' Center Outlet 4.25' x 7.88' Oval x 16' Long Body 21' Overall Length. Compact size is perfect for applications with limited space and can be used on a wide range of vehicles.

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.
