Finding the right exhaust system used to be difficult until now! SPD Performance created a configurable HX Series Cat-Back exhaust system that goes from mild to loud all while being drone free* inside the cab. Manufactured using 304 stainless steel mandrel bent 3" tubing and muffler, our Cat-Back systems are designed for maximum performance and longevity. Installation is a breeze with our systems being 100% bolt on with no cutting needed.
With our base system utilizing the factory resonator which gives your truck a nice growl. We recommend adding the resonator delete or performance resonator for full performance gains. The factory resonator tubing is 2 1/2 inches where there is noticeable performance gains with our true 3" resonator delete or performance resonators.
