Vortip wanted

[EricZ]

I'm interested in buying a vortip style insert but I think that the prices for a new one are ridiculous. Does anyone have a used one to sell and what performance and sound changes should I expect on a '00 WR 400? Are they difficult to make at home and still emit 94db or less?

I just bought WB vortip for my '00 WR. It seems only slightly louder than stock and pulls a bit harder as well.

It seems good for woods riding, but you are going to want to pull the baffle entirely for moto work.

I think it is worth $70.
