SPD'S GX Series Cat-Back Exhaust has shattered all expectations! Designed to be AGRESSIVE but DRONE FREE sound that you will love. Manufactured using 304 stainless mandrel bent 3" tubing and GX Series stainless muffler, these cat-back systems are designed for performance and sound without the raspy note at high rpms.

Our GX Series mufflers use sound wave canceling technology without glass or metal fiber materials. Fiber/mesh materials will breaks down from harmonic vibrations, which is why the other brand's exhaust systems will get louder each year.

Installation is a breeze with our systems being 100% bolt on with no cutting needed.

With our base system utilizing the factory resonator, it gives your truck an aggressive exhaust note. We recommend adding the performance resonator delete for full performance gains. There is noticeable performance gains with our true 3" resonator delete. Factory resonator tubing is 2 3/4.
