Description

Developed for truck applications and other applications that require a long body muffler. This muffler is considered a "Touring" muffler when compared to the 6.75" diameter x 24" Long body BORLA(r) Specialty mufflers and used on the same application. Un-notched necks are designed for weld in installation. Alternate muffler with Notched neck is 401662. Use 1" wide band style clamps 18330 (clamps not included). Reversible design for installation flexibility. High-quality T-304 austenitic stainless steel for superior corrosion resistance. 100% welded construction for strength. Free Flow design for improved performance. High-temperature continuous-filament fiber (CFF) acoustic material for sound control. Natural mill finish can be brushed or polished prior to installation. Best of all, it's made in the USA and backed by BORLA(r) 's Million-Mile warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
