Ron, do you have an IO390 with the Vans exhaust through the tunnel, or a Superior XP400 with 2 pipes, and if so, in the tunnel or below the floor boards like an RV 7?
I have a Superior with pipes pointed below the floor boards. I haven't noticed heat, but have some exhaust drumming, particularly at high power settings, and was wondering about downward diverters.
