The MRT Extreme Cat-Back Exhaust delivers a straight-through design to deliver maximized performance and a truly aggressive sound for your ride. Now available for the 2020+ Ford Explorer ST, the Extreme Series from MRT is the perfect choice for those who want to get noticed and experience improved performance. True to MRT fashion, these exhausts are handcrafted proudly in the USA in Plymouth, MI. They are crafted using only the highest-quality stainless steel and CNC mandrel-bent for the best results possible.

What makes the Extreme Series a full cat-back system? MRT has designed lead tubes that connect to the Explorer ST’s factory downpipes for a true 2.5-inch exhaust that provides a fuller and deeper sound to go along with its increased performance. This system should fit other aftermarket downpipes, too, provided their fitment follows the same OEM attachment points.

The Extreme Cat-Back Exhaust consists of “maximum everything” ­– larger tubes, premium materials, louder exhaust tone, and more performance. This stunning, handcrafted system is made entirely out of 2.5-inch diameter T304 stainless steel using the H-pipe design and sporting 4-inch angle-cut quad tips. Choose from polished stainless-steel tips for that classic look or blackout tips for a more stealthy appeal. The key feature of this cat-back is full, consistent exhaust flow which results from MRT’s straight-through design for maximum power and sound. Speaking of sound, you can certainly hear the difference with this system because it is the loudest MRT system available for the 2020+ Explorer ST. While it may have an aggressive tone, this exhaust causes minimal drone inside the cabin so you can still enjoy a comfortable ride.

Like all MRT exhausts, the Extreme Cat-Back System for the Explorer ST is designed to complement the SUV. It is engineered to increase function and reduce weight to allow for performance improvements without straying from the Explorer’s natural DNA but also standing out from others on the road. If you are a performance-minded person, the MRT Extreme Sport Cat-Back Exhaust is the way to go to enjoy a bold tone with proven gains for your Ford SUV.
