Vortip
Truespode, I'm not very confident the Vortip will fit a YZ. It's made to replace the factory WR ex. insert. I've got one on my 426. It has a 1-7/8 o.d.. You may be able to drill a small hole to match the mounting lug,but check your outlet dia. before ordering. Fineline suspension and I believe Baja Designs are licensed by White bros. to make them. I found it very quiet(I could not hear my exhaust over the airbox noise, lid off) but I had a bad stumble i/4-1/3 throttle. I removed the tubes even to where the twisted baffle starts,and found most of the response I'd lost. it's not harsh but does make some noise at WFO. good luck, Jonny 426
