I sometimes get a little bit of fumes as I start to take off from a long red light, but it's very faint. I haven't noticed any fumes going down the road.
I'm hoping not to have to do that but will if I need to. So far the pipes haven't gotten hot enough to remove skin if your leg touches it, but you do feel the heat.
I promise you that it does. The passenger side has done branded 3 people.
