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 performance look of the Explorer ST.

If you'd like the full system sound, add the MRT Sport Touring H pipe for an performance upgrade that breathes and exudes a deep rumble to give an exceptionally fun driving experience - MRT Part #90R227 For Explorer adventurers looking for maximum sound and maximum performance, the MRT Extreme cat back was designed with you in mind - MRT Part # 90R228.

The MRT Extreme axle back is the loudest MRT exhaust for the Explorer so you can certainly Hear the Difference and is engineered with minimal drone for a comfortable driving experience. Base systems include T304 polished SS 4" tips and 2.5" mandrel-bent tubes. 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.

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.
