    Electric Exhaust Cutout Systems

  • 2.5"

  • 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 race ready growl when needed. They are electrically controlled exhaust valves that 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. These electric exhaust cutouts fit any car or truck, from old-school muscle cars to high-tech imports permitting space given. Kits include an innovative V-band style clamp so the turndown angled tip can be rotated 360° for a perfect look. Cutout systems are available in single or dual exhaust kits.  Choose from weld-in or bolt-in styles with available finishes in either stainless steel or aluminized mild steel.

    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.

    Rated 5 out of 5 by from The most complete kit I have used ! Great quality. The turn downs with band clamp saves welding time to complete the job. One click open/close feature is a plus.

    Rated 5 out of 5 by from High Quality Product! Installed these on my '72 SS nova, small block car - sounds angry when open! I did have to cut the collectors off, turn, and weld back on, as there is zero adjustment and they are not positioned to have the cutouts parallel to the ground, my car is lowered and this gave me the clearance I needed. All components are really high quality, the one touch open/close is a great feature as well.

    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.
