Simply put, the faster exhaust gases move out of the engine, the more horsepower your car will make. When your exhaust shut-off is on, you bypass the muffler and increase the speed at which the exhaust leaves the vehicle. Therefore, open exhaust ports can increase the horsepower of the vehicle. So an exhaust cutout has two great benefits for any speed reducer looking to improve its ride. A properly installed exhaust shut-off provides an electrical connection to the dash. From there, the driver can open and close the exhaust at the touch of a button. When you open the exhaust, the exhaust bypasses the muffler, releasing a lot. You can then seamlessly close the vents for a perfect blend with the other car next to you. With the exhaust port, you can easily switch from the racing sound to the regular engine.
