I saw on Pypes Instagram story today that they have a dual exit exhaust for the Ranger coming soon. I don't have any info but I saw they teased a picture.
Now that we know GVWR and max payload, that should give us the curb weight.
Confirmed GVWR is 6050 lbs and confirmed payload capacity of the 4x2 model is 1840 lbs.
Using the formula Gross vehicle weight rating - curb weight = payload capacity
That means curb weight should be about 4210 lbs.
