Manual cutouts?

[Munch]

How do these work, do you have to crawl under the car and open them or what?

They have a pull cord to open and close them. I have only seen them on bracket race cars.

Works like an old manual choke.

An exhaust cutout for your Chevrolet Corvette gives the exhaust a throatier sound. It can also provide extra power when you need it.

How does it work? It's like this: a "Y"-shaped section of pipe is installed along the exhaust pipe of your Corvette. With the cutout installed, you flip a switch or operate a lever to either allow the exhaust to bypass the muffler, or not. The switch or lever opens, closes, or feathers the opening. In the open or partially open position, the exhaust gases escape before going through the muffler and the entire length of the exhaust pipe. This reduces pressure in the pipe, providing more torque and horse power. It also gives you more and better sound from your Corvette engine.

Usually a cutout is installed immediately before the driver's side section of the exhaust pipe where it meets up with the passenger side of the pipe. The cutout, with a straight section and a "slanted" section, is positioned so that straight section is in line with the exhaust pipe and the slanted section faces down toward the ground and the back end of the car. Another place to install it is near the rear of your Corvette right before the muffler. A muffler shop can perform the installation as well as the shop from which you purchased your cutout. The installer simply removes a section of the exhaust pipe and installs your cutout in place.

Cutouts can be operated manually with a lever, or electronically via a toggle switch from inside the passenger compartment. You can also operate a cutout with a wireless remote, some of which have an optional RPM control.
