Overall the unit is ok but the directions could be way better. My big issue is that this was supposed to made for my particular vehicle. Given that, I'd like to think the directions would instruct you to not mount a tread in line with the exhaust, even if the exhaust was a bit away from tread. Or include some sort of heat shield to eliminate the melting of the plastic tread. Now I look like I half assed it or cheaped out by only mounting one tread?
