A: we designed this with longer header to better clearance of the trex 700 fuel tank, also we do once piece header design to eleminate o-ring usages that
watches causes leakage. Also we design baffle attachement to the pipe walls by welding not press fit to ensure the baffles are not getting loose due to vibration. These add up the weight. It is 290g including everything
and the hatori is 260g. Yes it's about 15% more in weight but it offers a lot of features
cheap and advantages besides the great price
