Those missing the brawny growl of the Ford F-150 Raptor’s first-generation 6.2-liter V-8 won’t find much consolation in a redesigned exhaust system on the third-generation off-road behemoth that continues to be a V-6, but Ford is taking a whack at giving the twin-turbocharged 3.5-liter V-6 a throatier howl with a redo of the 2021 Raptor’s exhaust. A new exhaust system for 2021 includes mechanical trickery to change how the 2021 Raptor sounds, including a “trombone” mid-pipe loop, X-pipe and active valves that change the sound level depending on drive mode.

To start, the exhaust is now 3 inches in diameter, up from 2.75 inches, according to a Ford spokesperson. The new trombone loop creates an equal-length exhaust between the driver and passenger exhaust by adding extra length to the passenger-side exhaust run. From there, the exhaust enters a single muffler and exits into the active valves that Ford says allow for a “true pass-through muffler.” There are three pipe exits from the muffler, two of which are valved and go straight through the muffler, according to Ford, and the third is the quiet pipe that the exhaust flows through when the valves are shut. All three merge into an X-pipe (versus an integrated mixing chamber inside the prior gen’s muffler) and then the pipes separate into the dual-exit tips.

In all of our Raptor acceleration and off-road testing, I never thought the twin-turbocharged 3.5-liter high-output EcoBoost sounded “bad” from behind the wheel, but a lot of that was masked by the electronic augmentation inside the cabin, and just a very livable, quiet interior. On the outside, however, while throatier than a regular 3.5-liter EcoBoost, to my ears it was a wimpy showcase of the powerhouse engine putting out 450 horsepower and 510 pounds-feet of torque. 

Below is a reminder of how the 2017 Raptor sounded from our Raptor Sights and Sounds Video (jump in at 1 minute, 28 seconds), and compare it with a Ford-provided sample of the 2021 Raptor’s new exhaust. There’s still more to hear from the Raptor as we learn more, like how much extra power and torque will be expelled through those pipes (power and torque figures are currently hush-hush).
