Bend a piece of the same strap at a 90 degree bend, weld to the cross strap and drill a hole at the top of the 90 degree bend. Use an automotive rubber strap and attach to the cross tube behind engine and clamp with an adell clamp. I have had mine on for three years with no problems. Oh by the way, I never used Vettermans exhaust mounting kit right from the start.
