MRT Deep & Mellow Cat Back Exhaust (91K104) - 2015-2020 F150 2.7L 3.5L EcoBoost & 5.0L
Upgrade your 2015-2020 Ford F150 with the MRT Deep & Mellow Cat Back Exhaust and enjoy a refined performance sound that enhances your truck without overwhelming it. Designed for drivers who want a deeper, more aggressive tone while maintaining daily comfort, this system delivers a smooth idle rumble that builds into a strong, confident growl under acceleration.
Engineered for both EcoBoost and 5.0L V8 applications, this system features 3 inch mandrel-bent tubing and a straight-through muffler design to improve exhaust flow and reduce back pressure. The result is increased horsepower, torque, and overall efficiency. Constructed from premium T304 stainless steel, this exhaust is built for long-term durability and corrosion resistance. It is finished with dual 4 inch double-wall stainless steel tips, with an optional black matte finish available for a more aggressive appearance.
Handcrafted in the USA, the MRT Deep & Mellow system offers a balanced sound profile that is louder than stock but controlled enough for everyday driving. With minimal drone and a clean bolt-on installation, this cat-back system delivers the perfect combination of sound, performance, and comfort for your F150.
