Delkovic...but as supplied its no good for the Xciting500. its packed with fiberglass which promptly melts goes hard , breaks up, falls out...after 4 repackings with alternative fiberglasses per aftermarket shops it is now packed with stainless steel wool,,initially too loose and all went up one end leaving 75%of the inner pipe unmuffled...the noise!!!! too much man too piercing! so repacked again last weekend with lots more stainless wool packed firm..and now !? lovely. a deep basss mutter on the road at speed and nice whump whump at idle
...I think Superwool ( Ceramic fibre) would probably have been ok for the temperature as well but its harder for me to get
