It sound better than I could have imagined. I was looking for a deep sound, with NO drone (yes folks, there is ZERO drone in the cab when cruising) but when I get on it it is loud and deep. This is the exact sound I was going for an I acheived it. At idle you can hear it but it's not loud in the cab.
I went with the Magnaflow #12259 18" muffler with a 4x12" Magnaflow rolled tip and the stock pipes.
This is my first mod to the truck, but I have only had it for 2 weeks today. A tune is next! Thanks guys!
