SPD Performance 2015-2017 Ford Expedition / Navigator 3.5L GX Series Stainless Single 3.0IN Exit Cat-Back Exhaust

Our GX Series Cat-Back Exhaust has shattered all expectations! It is designed to be aggressive but has a 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 will give your Expedition or Navigator the most turbo whistle possible!

Our GX Series mufflers use sound wave canceling technology without glass or metal fiber materials. Fiber/mesh materials break down from harmonic vibrations, which is why the other brands’ exhaust systems get louder each year. All SPD exhaust products are proudly built in the USA.

Installation is a breeze, and our systems are 100% bolt-on without cutting.
