•The intake and exhaust are tuned and tested to provide a boost at certain engine speeds. They are also designed to have very low restriction, and there are no mufflers or catalytic converters to slow the exhaust down either.
750 HP engines with Unrestricted Headers that dump into a Y pipe then split off (around 3" in diameter) exiting out the side of the car, no mufflers. These systems are the same for all makes and they are designed to make HP and torque exclusively! They are loud and proud!
