The Borla 60714 is a universal T-Flow muffler with a single 2.5 in inlet on the side of the body and dual 2.5 in offset outlets, one on each end. Its internal flow follows a T pattern, and the reversible design adds installation flexibility. It uses 100 percent welded T-304 austenitic stainless steel construction, a free-flow design for performance, and high-temperature continuous-filament fiber (CFF) acoustic material for sound control. The natural mill finish can be brushed or polished before installation. The un-notched necks are designed for weld-in installation; if clamping, use a 3 in wide band clamp (part 18004). It is made in the USA and backed by the Borla Million-Mile Warranty.
