Valves opened (Race mode): When car owners turn on the race mode (valves opened), the gas go through the section of straight pipes, this is where you get this incredibly race sound and performance gain in full throttle and it’s straight pipe all the way.
Valve closed (Street mode): When the valves are closed, the gas are redirect to the muffler section, this is where you turn the volume down in quiet mode without disturbing the neighborhoods, it’s perfect for someone who doesn’t want the sound to be that loud all the time, and it helps a lot with eliminating the drones inside the car and more comfortable driving.
