The pipe fit perfectly first time. Just needed the bracket which I stated somewhere near the first post. Power is very linear, strong all the way through, there doesn't seem to be any particular point which is over achieving, but also no under acheiving. I'm on holiday atm but have had cdi trouble from a fragged stator again, so I'm yet to really pin it as the spare rm125 cdis I have both seem to sputter at high rpm (odd considering they share the same stator coil, according to electrex that is!) Will give a full review plus videos in about 2 weeks.
For the tarts out there (myself included) the sound is lovely, the rattle is gone, and the high pitched *ding* has gained some depth, the first time I've ever had a 2 stroke turn heads on the street!
Really is worth the money, its the cheapest pipe put there, solid as a rock, very smooth running (my idle has improved greatly), and won't rust!
