thanks pow. but regardless i tell you. I used to have a car with a modified engine. Among others modifications, i had removed the muffler and improve the exhaust. The sound inside that car was spectacular and super loud.
Some racers also, with the time, loose the hearing capability due to strong noise. The audio that you hear in real rally cockpit cam on online videos, is not the real sound either. Example. Fire 9 mm gun in real life vs youtube video. Even with ear protection, the sound is explosive.
Sorry for my english, hug!.
