FAQs About Axle-Back Exhaust Systems for 2021-2022 Ford Broncos with 2.3L and 2.7L EcoBoost Engines
What years and engines does this exhaust fit?
This system fits the 2021 and 2022 Ford Bronco equipped with either the 2.3L or 2.7L EcoBoost engine. It does not fit the Ford Bronco Sport, which is built on a different platform.
What does the MRT Trail Rated Single Tip Axle-Back sound like?
At idle, it produces a nice, soft whir in the background that is balanced rather than overpowering. As RPMs climb, the tone becomes sporty but stays subdued, and you can hear some turbo whoosh and whistle from the EcoBoost engine. Wide-open throttle brings out a more confident, enhanced sport sound.
How much drone does this system produce on the highway?
MRT rates the drone at a 1 out of 10. Owners consistently describe the sound as present without being harsh or inappropriate, making this system comfortable for daily driving and long highway trips.
Will this exhaust improve performance and fuel economy on my Bronco?
Yes. The straight-through muffler design improves exhaust flow on both the 2.3L and 2.7L EcoBoost engines, which supports gains in performance, sound character, and fuel economy compared to the stock exhaust.
Do I need a tune after installing this axle-back system?
No tune is required. This is a direct bolt-on replacement that is fully compatible with the factory ECU and requires no additional programming or calibration.
How long does installation take, and what tools do I need?
Installation takes approximately 60 minutes using only common hand tools. Owners regularly report an easy, fast installation, making this an accessible upgrade for any backyard mechanic.
What tip finish options are available?
This system is offered with a single tip in either a polished stainless steel finish or a Black Ops matte finish for a more blacked-out, aggressive appearance.
How does this compare to the turn down tip Trail Rated option?
This single tip version delivers the same Trail Rated sound profile as the turn down tip version, part number 90R232. Choose this single tip configuration if you prefer the classic rear exit look over a tucked, turn-down style.
How does this compare to the King of the Hill series?
The Trail Rated Single Tip Axle-Back is quieter and more refined than MRT's King of the Hill series, which is built for owners who want a more aggressive, street performance sound under most driving conditions. The King of the Hill series is available in turn-down tip, part number 90R230, single tip, part number 90R234, and dual tips, part number 90R238.
What other Bronco upgrades pair well with this exhaust?
Many owners pair this axle-back with MRT's no-drill Ford Bronco Hood Struts, part number 80K110, which eliminate the factory prop rod without drilling any holes in the vehicle, completing the full MRT upgrade experience.
