MRT Extreme Cat Back Exhaust with H-Pipe (90R228) - 2020+ Ford Explorer ST 3.0L EcoBoost
Take your 2020+ Ford Explorer ST to the next level with the MRT Extreme Cat Back Exhaust, engineered for maximum sound, maximum performance, and maximum presence. As the most aggressive system in the MRT Explorer lineup, this cat-back delivers an unmistakable deep muscle tone that commands attention at idle and unleashes a powerful roar under throttle.
Constructed entirely from premium T304 stainless steel, this system features 2.5 inch mandrel-bent tubing and a high-flow H-pipe design to improve exhaust scavenging and reduce back pressure. The straight-through exhaust layout ensures consistent, unrestricted flow, helping your 3.0L EcoBoost engine produce stronger performance and faster response while maintaining a deep, smooth exhaust tone.
Finished with quad 4 inch angle-cut tips, the MRT Extreme system enhances the aggressive styling of the Explorer ST while delivering the loudest exhaust note available for this platform. Despite its high-output design, MRT engineering keeps interior drone controlled, making it surprisingly livable for daily driving while still delivering race-inspired sound when you want it.
