Treat Your 3-Inch Exhaust to One Touch Electric Cutouts and Wow the Crowds

Exhaust cutouts are hardly anything new. Your grandfather was using cutouts on his hot rod back in the 1950s. The only difference was, back then you had to climb under the car and deal with block off plates, wing nuts, and hot exhaust systems to “uncork” the exhaust and hear all the horsepower. Over time the thrill of exhaust cutouts has ebbed and flowed with the automotive hobby, but today they are popular as ever thanks to the updated design of electric exhaust cutouts that can be controlled from the driver’s seat, where you stay nice and clean, and you won’t burn your fingers.

Adding electric exhaust cutouts doesn’t have to be a difficult job. Take the Granatelli Motor Sports kit for example. A simple slip-fit design means installation takes nothing more than cutting  small section from your car or truck’s 3-inch exhaust to fit the Y-pipe into place and then bolt up the cutout motor assembly and the turndowns. Route a little bit of wiring and find a location for the switch in your dash or console and you’re ready to hit the streets! High quality stainless and aluminum construction means the Granatelli kit is tough and can be used even on your daily driver.

Granatelli Motor Sports’ tough “Smart Chip” electronics means you simply touch the switch once to open or close without the fear of overrunning the cutout motor and damaging the gears. There's no need to hold the switch down for the cutout to fully open or close. The standard V-band flange on the exhaust turn down allows 360-degree rotation of the 45 degree turn down outlet, providing the installer with the ability to “phase” the exhaust system pulses inboard or outboard as necessary for best sound.

Turn heads at the next cruise in when you roll in with your exhaust cutouts open and your engine’s exhaust chop singing the sounds of horsepower! Then close ’em up for the ride home without raising any eyebrows (or getting out of your car for that matter!).
