Optionally pre-welded to your downpipe is a DHM electric cutout which allows you to take full advantage of your Cartuning Turbo Kit. The factory exhaust system is extremely restrictive. By releasing backpressure with this electric cutout, you can open up as much as 50 WHP (dyno proven). The cutout is controlled from inside the vehicle, and can variably open anywhere from closed to 100%. Not only can you control the horsepower of your vehicle this way, but you also have full control of the sound from mild to wild. Cartuning has achieved 500 wheel horsepower with an electric cutout on a stock exhaust system. This is a much better alternative than an aftermarket exhaust. Video clip coming soon!
