Sounds absolutely amazing on the 5.0 coyote! It definitely is much louder inside the cab but I knew that going in. Cruising at highway speeds is very manageable. Cold start-up is very loud and cackles nicely. The rest of my exhaust is stock.

Bout this for my '14 150 5.0. Someone I know in my family has this on their ram and it sounded great so I decided to get one for my truck. Deleted my resonator and replaced this for the muffler and I am very happy. It was obnoxiously loud for a week and since then it has broken in and quieted up a little. Also has made my truck gain quite a bit in fuel economy even in the cold weather.

This muffler is a gift from the loudest Gods. IT doesn't sound ricey at all and is all low. ITs louder then a Porsche. This is loud though like it will vibrate the car and you will ask people to speak up and you cant really hear people on Bluetooth and they cant really hear you but it is so worth. The start up is beatiful

I usually don't do reviews, but I'll tell you all out there that the super 10 muffler is the one!!! I have an 03 silverado 4.8l and going from stock to this bad boy;whew!!! Huge upgrade. Truck instantly went from bland to beast. And shipping from autoanything was fast and prompt with prices that can't beat.

I had a 40 series flowmaster single in/out with stock tailpipe on my GMC 5.3, it sounded good at idle but disappeared at WOT when I really wanted to hear it, so I bought the super 10 to replace it, I dumped it right by the rear axle, this thing sounds amazing, exactly what I was looking for, I find myself flooring the gas peddle just to hear that amazing exhaust rumble. I couldn't be happier and if you are scared it will be too loud, don't be, it isn't super loud, but it is deep/aggressive.
