All depends on what he does and how he rides. Requisite for the yfz is to do the cam mod, remove lid, and add ron woods intake.
As far as pipes go...

For MX: TC

For Dunes: ESR or Jardine

For all around: Sparks or Duncan

Keep in mind though, all of these are loud.

He is a beginner. he will mostly dune ride. He does want want to mod it as he gets to know the bike and how to ride. money is not a issue for him.

Tell him to get the tc pipe and a set of ear plugs and he will be good to go. [img]i/expressions/face-icon-small-happy.gif[/img]

Ok thanks but I got 5 opionions, noise is not a issue. can someone tell me if there is a diff between the 5 choices? witch one will work the best for the long run in mild mods.

I think it's dirt wheels that just did a huge pipe test for the YFZ. Go check it out. To be honest it looked to me like they are all in the same ballpark with horsepower within 1hp of each other and torque in the same range. That said I've been really happy with my Alba set up and it's alot cheaper then most.
