Muffled tuned pipe to suit (I think) .61 engine in good clean condition, purchased from USA for more than double what I'm asking here.
Total length is 380mm, max dia ~ 38mm, diameter at header ~ 19.5mm, exhaust outlet ID ~ 9.5mm.
What you see is what you get, I haven't used it myself, not sure if it has been used by previous owner, doesn't look like it as it is clean inside, no carbon build up or anything.
$80 including postage in Australia.
