Product Details Technical Specs Installation Instructions
Experience outsized sound and power with this Ford Explorer performance exhaust system. The Explorer MRT Extreme Axle-Back Exhaust has a loud, deep muscle car sound and is handcrafted in corrosion-resistant T304 stainless steel. This system has a straight-through muffler delete design that is all about providing maximum flow and maximum performance that matches the performance sound and aggressive look of the Explorer ST.

The MRT Extreme Axle-Back is the loudest MRT exhaust for the Explorer so you can certainly Hear the Difference. It's engineered with minimal drone for a comfortable driving experience. The increased exhaust flow thanks to large 2.5-inch mandrel-bent tubes means you also receive a noticeable jolt of horsepower and better fuel efficiency.

Our Ford Explorer performance exhaust has great looks, too. Base systems include quad T304 polished stainless steel 4-inch tips with double walls and beveled edges. If you're looking to give the tips more of a stealth-like look, a Black Ops black matte tip finish is available for an additional fee. Both tips are a durable and stylish addition that will Get Noticed as you're leaving the herd behind.

MRT has other ways to customize your Explorer exhaust setup. If you'd like the full system sound, add the MRT Sport Touring H pipe (MRT Part #90R227) for a performance upgrade that breathes and exudes a deep rumble to give an exceptionally fun driving experience. For Explorer adventurers looking for maximum sound and maximum performance, the MRT Extreme Cat-Back (MRT Part # 90R228) was designed with you in mind.

Whatever system you choose, it's inspected a minimum of four times before it leaves MRT so ensure it meets our high standards for performance and quality. You also receive a limited lifetime warranty and superior service.

Application: 2020+ Explorer 2.3L EcoBoost , Explorer ST 3.0L EcoBoost

Had the MRT axle back with resonator delete installed. Little to no drone and boy does it have a loud sound when you get on it! Highly recommend, forget about getting a Borla or Corsa cat-back and go with this. You won't be disappointed!

5 of 5 Love it! January 20, 2021

I have a 2020 Explorer and wanted to hear more exhaust. I bought this system and had it installed.
Now every time I step on it, I hear the exhaust.  Love it! My installer said he'd install another MRT system in a heartbeat - great fit and quality.
