I didn't like this muffler, it was too loud in the cab. Whenever it went into overdrive, you couldn't take it with your ears, I had to turn it off. I only had it for a few days because we were going on a long trip. It's in my garage with stickers. The stickers didn't even burn! His. Waste of money because we can't use it. With Chevrolet Silverado 2017!
