Expert Reply:

Yes, the MagnaFlow Black DPF Series Filter-Back Exhaust System # MF17067 will absolutely fit your 2018 Ford F-350 Super Duty Crew Cab with a 6.7L Diesel, and it will do more than just give you a unique sound. The MagnaFlow will also improve your horsepower, torque and gas mileage because it uses mandrel bent tubes.

What this means is that the diameter of the tubes on the muffler remain the same throughout, as opposed to mufflers with tubes that get smaller when they bend. To oversimplify it, when using the MagnaFlow # MF17067 on your truck, the airflow will not be impeded, leading to the performance gains you are seeking.

If you really want to improve the performance on your 2018 F-350 with a 6.7L diesel, the best way is by adding the MagnaFlow along with a performance chip.

The Superchips Flashpaq F5 Performance Tuner - Ford # SU1845 and Edge EvoHT2 Hand-Held Performance Tuner - Ford # EP16040 have settings that allow you to change the HP and Torque, including a Performance setting on both which will give you up to 120 HP and 220 ft/lbs of torque.

They also have settings for towing and economy along with other options such as adjusting transmission shift points; both simply plug into your OBD-II port, making them very simple to use use. As a note, these two tuners are legal in all states except California.
