DAF XF Euro 6 Stock reworked & Open Pipe sound

The first seconds of this video are with the stock sound that i have fully reworked. Then, once swapped my engine in a shop, the open pipe sound is enabled.
I totally reworked the standard sound of this truck to make it sound deeper and realistic, then added my tires/bearings sound. The air lift axle has been improved too, now it finishes in a fade, progressively.
Also, i have added two extra engines which are open pipe.
Those new engines have more torque and power, they are “chipped” and the gain of power/torque is realistic too. it’s nice for pulling heavy haulage.
