To CLear things up a bit. I have re-enforced the bottom of the mounts with 1/4 steal because I was afraid of just that. My headers are ceramic coated and have no heat issues. I bought copper gaskets from the local speed shop and have not had to retorque them since the first 250 miles or so. There is also a summit racing heat plate/muffler guard over each Hushpower II muffler thus keeping heat to the floor board to a minimum.
I am running a 700r4/Orion HD. It was getting pretty crowded between the frame rails with the fuel pump, tranny cooler + fan, Battery isolater and what have you. OUtsied the fender was the only way to go for me.
To each there own.
Idus....................did you steel that steal?
