It's raw and sounds ten times better than the mufflers I had. I read a review that said this drone spins at around 1-2k RPM, which is quite different from what I've experienced with throttle silencers which spin the drone at around 2-4.5k RPM. min approach Since the pipe size on the car is 2 1/4 inches and the pipe size for it is 2.5 inches, it complements the car well. I already have a Cherry Bomb muffler under the car instead of the resonator I had.
