What Are the Benefits of Exhaust Cut Outs?

Save

Factory exhaust systems can be restrictive to exhaust flow, and aftermarket systems can be expensive. For those who desire the greatest possible exhaust flow for their car without the cost of purchasing an aftermarket exhaust system, a cutout might well be the ideal answer.

Function

  • Exhaust cutouts are used to vent an engine's spent gases to the atmosphere without having to pass it through the mufflers and tailpipes.

Placement

  • Cutouts are large butterfly valves placed in an exhaust pipe, ideally as close to the engine as possible.

Benefits

  • Exhaust cutouts give all the benefits of a completely open exhaust and the massive decrease in backpressure concordant with it, but allow the user to cap the cutout and return to a street legal exhaust configuration at will.

Electric Cutouts

  • One of the best exhaust upgrades for any car is the electric cutout. This type of cutout links to a switch inside the car, allowing the driver to switch from a street-legal to a full-race exhaust at will.

Warnings

  • Be careful where you place your cutout. Short exhaust systems can spew still-burning fuel from the opening under rapid deceleration. Pay close attention to the location of fuel and electrical lines when installing.
