The Borla 401624 is a universal long-body muffler developed for trucks and other applications that require a longer muffler, and it delivers Borla's classic S-Type sound. The un-notched necks are designed for weld-in installation; if clamping, use 3in wide band clamps, and the matching notched version is 401625 (use 1in wide band clamps). The reversible design adds installation flexibility, and the body uses high-quality T-304 austenitic stainless steel with 100% welded construction and a free-flow design. High-temperature continuous-filament fiber acoustic material controls sound, and the natural mill finish can be brushed or polished before installation. It is made in the USA and backed by Borla's Million-Mile Warranty.
