I've been wanting to convert my M4 mid mounts to a high mount, I've gotten the measurements and like the way it looks in my head, but the only problem is my wife rides on the back a lot and she is worried about the exhaust being closer to her legs is this a problem or not?

 

My lady says that not really. She had ridden with me, (400 plus mile trips) with both types. I went from low yosh to high jardines. She kinda liked that the foot pegs were were set a bit wider than stock, but she is tall so might not work for all.
