When I recently replaced the exhaust hoses between the riser and the fiberglass mufflers, the originals were soft type (without wire). The stuff I bought locally was wired, which was all they had in stock. The dimension I used on mine was 20". When the guy at the store was cutting off my section (only sold it in 12" increments) I heard some sort of power tool in the back. When I inquired, he said he used a chop-saw (circular cut-off saw). I had an 8" chop saw and so I tried it as well. A bit scary, it easily cuts the rubber, and it did cut thru the stainless steel wire as well. I highly recommend the safety glasses for that task. I could only get my old pair of kleins to cut the wire by stomping on handles against the ground. Man that stuff is tough. I would have preferred the soft type hose as well if I could have found it.
