    I am happy with the way the exhaust sounds, my issue is the the muffler hangs lower than the frame of the truck. I worry about bottoming out on the muffler for how low it hangs. My truck is lowered, it would be better if the muffler was more of a oval shape, I’m afraid of bottoming out and tearing the exhaust out from underneath my truck
