     Race Ready with a Flick of the Switch

    The Granatelli Electric Exhaust Cutout Systems offer the best of both worlds for your exhaust! Choose between a quality OEM sound for street use and the ability to switch for a wide-open racing growl when needed. These electrically-controlled exhaust valves mount to all standard flanged 3-bolt cutouts and can be opened and closed from inside the cockpit with Granatelli's innovative "one-touch" flip switch.

    When using the convenient interior-mounted switch, you can go from street tame to wide-open power without having to hold down the switch. Depending on space allotment, these electric exhaust cutouts will fit into any car or truck, ranging from old-school muscle cars to today's high-tech imports. Kits include an innovative V-band style clamp so the turndown angled tip can be rotated 360° for a perfect look.

    Single or dual exhaust cutout systems are available in weld-in or bolt-in styles for round or oval tubing, with stainless steel or aluminized mild steel finish.

    Rated 5 out of 5 by from Awesome exhaust cutouts This is a complete system that is fairly easy to install and gives you options of different ways to install it. The electrical part is simple to hook up just requires running wiring in a safe manner which is also fairly easy. Once it is all installed just hit the switch and it opens the exhaust which sounds awesome and hit the switch again and it instantly closes like it was not even there. I can't recommend this enough and for the price it is great. And one more important thing the whole system is made of Quality Parts not some cheap China part that will break after half dozen uses.

    Will any  momentary switch work with this system or do you have to use the switch that comes with it?

    Is it a single switch to operate both cutouts? It looks like there is two.

    Asked by: BeefSupreme
    There is one main connecting harness that has one switch going to the cabin.
