...and dust. Lots of dust. But would guess that the sound bouncing off the ground and up into a vehicle is going to be a lot different than a motorcycle. Turndowns do sound a lot different on/off-road too. If you don't mind the dust, probably won't be much of an issue. But why not put a tip on the end of that exhaust to turn it backwards, twisted off to one side or the other so it doesn't cook the tire?
