It uses 100% welded T-304 austenitic stainless steel construction that will never rust, a free flow design for improved performance, and high-temperature continuous-filament fiber acoustic material for sound control. The natural mill finish can be brushed or polished prior to installation. Made in the USA and backed by Borla's Million-Mile warranty.
