    Exhaust Cut-out?

    I just recently put a cut-out, is it ok to leave it off at all times. I do like the way it sounds. Or is it bad? I dont see how, but could it hurt the engine? Car is all stock, just have a lid on it.

    I have mine open 99% of the time for about 4 years. The car was actually sold off a dealer lot with an open cut out. The only time I close it is when I go on long trips on the highway. 6th gear at 80mph there is a nasty drone.

    I'm about to have a cut-out installed on mine (cam and bolt-ons) and the only time I'll have it closed is coming/going in my neighborhood at night/morning, and on long trips.

    A catalytic converter (colloquially, "cat" or "catcon") is a device used to reduce the toxicity of emissions from an internal combustion engine.

    I've heard to many stories of electric cut outs leaking so i've stayed away.

    the install also has to be more beefed up with heat tape, but thats the only thing i heard about that the wires buring up,

    and the motor is weak, from what i heard

    Yes, they give you a plate cover. There are studs sticking out of it, you slip the cover over the studs, then you put some wing nuts (provided as well) and tighten them down.
