Hi Rik, I had an original pipe on my Traveller when I brought it, but aft awhile an annoying rattle developed inside the the can. I took it off so's to take a look at the problem & could not believe how bloody heavy it was.. Found that the baffle was loose inside, cut can open & took baffle out, then folded & riveted an alloy sheet around it, sounded pretty awesome, but I could not get outa my head how heavy it was, after reading alot of tuning info on a MuZ Skorpion forum (
http://mzskorpion.info/phpbb2/index.php ) I fitted a renagade can and link pipe from a 2003 R6, this had the baffle inplace and once rejetted with a stage 3 carb kit from Dale Walker of Holeshot fame, (
www.holeshot.com ) in the states much improved the bikes performance.. Dale Walker has many years experience tuning The Yam Engine & offers tuning kits & Exhaust Cans to meet all needs...
These Skorpz fly with alittle tuning, just don't over bore it as it leads to overheating probs & blown head gaskets, but then I amm running 113mm dia piston with 12.1 ratio.. poor ol'gal can't seem to keep her head, so I'm in the process of fitting a 22gauge copper head gasket & having both head & barrel machined flat... Will also be fitting a proper thermostate & housing from same R6/FZR..
I have also had the flywheel lighted & re-balanced, there is no remarkable difference in top end, still around 115mph on a good day, but 50 to 90 is increadably quick & the sound is juz phenomenal..
