i was told that the tdr would make me lose power by an engine builder who will go un-named .i couldnt help myself i had to find out for myself.so i purchased the tdr baffled model and found that this thing rocks!!!!! fitment
erfect ,just a tad thinner then stock but otherwise every thing lined up perfect.i must say for freestyle riding this thing rips ,my engine spins up that much faster and really compliments my wet pipe/flywheel combo,good low-end improvement.i can tell my engine is really breathing better ,it did affect my jetting a little making it leaner ,im in the process of adjustment now but i think its something that can be dealt with with just the screws.anyways thumbs up tdr.... oh yea did i mention it sounds bad ass!
