Sounds great like all the other Flow Master exhausts I’ve had installed! Highly recommend for a GM 5.3 engine.

I bought this for my 2016 Ford F150 V6. Even though is says it doesn't fit pipes can be made to make it fit. It has a nice throaty sound at idle and up to 5000 rpms on a V6. Much better than the stock muffler. I also deleted the resonator. Good product
