Can exhaust cutouts increase your engine’s power output?
Correct Incorrect To use exhaust cutouts on a street-legal car, you’ll need a system that lets you switch between the cutout and the standard exhaust, as most local regulations prohibit continuous use. Opening the exhaust early usually gives you a slight power increase, but it also makes the car much louder—so be prepared for the noise!
