I just switched out my older Ford Racing Stinger mufflers for the Ford Racing Touring mufflers. I'm almost 100% positive they are rebadged Borlas. So I figured I would make a little comparison video between the two for anyone thinking they want to quiet down there off road x-pipe. The biggest factor for me was I wanted a quieter startup and less drone, and the Touring muffler took care of both. I'm not worried about a little power loss by changing.
