Description

Its free-flow design is intended to improve performance, while the internal high-temperature continuous filament fiber (CFF) acoustic material manages sound output. The muffler features a natural mill finish that can be customized through brushing or polishing prior to installation. This ProXS muffler boasts a reversible design, offering installation flexibility whether your system requires a single inlet and dual outlets or vice versa. With a 2.5-inch center inlet and dual 2.5-inch outlets, its oval body measures 19 inches long by 4 inches wide by 9.5 inches high. Borla manufactures this muffler in the USA, leveraging their extensive experience as a leading exhaust brand.
