What is the best exhaust for a YFZ 450?

I need a USFS approved silencer for the YFZ 450. When it comes to horsepower what is the best silencer I can get?

It would be hard to choose. The YFZ hasn't been out long and I'm not sure that their are a lot of them with pipes and everything. But your decision should be pretty easy since you want a pipe with a spark arrestor.

They have about 10 pipes for the YFZ. So you would just have to look for one with a spark arrestor.

They have a couple pipes, and I'm sure one or two of them come with the spark arrestor.

Right now I'm running the White Brothers E-Series on my Warrior. At the time that I bought it, that pipe offered the most horsepower gain for the Warrior. I'm just wondering if the same is true for the YFZ.
Is anyone running the E-Series on their YFZ?
