sorry for the late response.. i have not tried it with the baffle in lol, right when i got it i pulled the baffle haha. but i think theres another video where he shows it with and without baffle in :)

but im sure its a huge difference in sound, the baffle was very big!

I think i'll go with the 14 inch one, maybe it is not legal in canada but at least it won't be so loud so cops bother me

the thing is there is no video of the klx on youtube with the delkevic exhaust, and i wonder if it is actually louder than the fmf q4

yah mine isnt legal either lol. i just went with the cheapest one so i could get some sound out of my bike haha

I hit 110 once but I would say 90-100 kmh
