I do use a straight thru style muffler as well . Quietens engine well without being restrictive .The discs also serve as a spark arrestor . An engine can produce sparks. Nobody wants to set the brush on fire !!!!! The discs run hot ..
Also ceramic coating on the header pipes will cut the radiant heat of the pipes by half .
U can use fibre glass header wrap but remember this overheats the steel that much it crystalizes and the pipe goes brittle 6-12mth life span .
Weld on or clamp on stainless heat shield is also an idea
U could weld on stainless shield to take advantage of any air coming off the engine to cool the pipes. Waste hot air directed out of the body.
