Granatelli 3.0in Aluminized Mild Steel Electronic Exhaust Cutout w/Slip Fit Band Clamps

Had it on the car a few weeks. High quality parts for sure. The y is 3 inch id on both ends so slips on easily and the clamps are pretty good as well. The wiring was just two wires. I installed it myself. The turndown is a nice touch and its v band style so its easy to loosen and adjust to your liking. Couldnt be happier with the product. No leaks. Just some shocked faces when I open it up at a light to hear the cammed ls1 chop away..

I brought the exhaust cut out to Midas Muffler and they did a nice job installing it, including the switch. I love opening the exhaust up when I'm pulling away from a light, then I close it up for quiet operation when I pull in the driveway. My wife still doesn't know that it's me that sounds like a race car down the end of the street.

Works great and allows me to have loud or “quiet” exhaust. I had to call the manufacturer though bc their install instructions vs the parts that are sent are not clear. They have not revised their install instructions and are still sending 384 extra pieces of hardware. That said, I’d buy it again.

Had this cutout for 3 years. Constantly broke and had to warranty it and ended up just rebuilding it with left over parts when they stopped accepting warrnty claims, which is fair. However just not great quality, customer support was lovely though. Got my moneys worth in fun.

Love it . Good quality . BUT the valve flap rattles when open on my truck and the valve shut still has exhaust leak by.

The exhaust it self was nice but the wiring was terrible all the terminals just broke loose the wire from the motor broke off after a day terrible experience I wouldn’t recommend
