Help me pick new exhaust - 06 WR450 Street

I have been looking around for a new full system for my 06 WR450 (street) - Cost is not an issue & I want to get carbon...

Been looking around & the new Yosh models seem pretty good but im unsure how they are power wise vs. say (White Brothers) Etc...

NEW 06 Yosh:

Alot of the sites only list YZ models & im unsure if they will fit on my WR & what years will match up.. (will 04 05 YZ pipes fit 06 WR ?)

Heres the ones I looking at:

Pro Series Tri-Oval TRS:

Pro Series TRC:

If it were me, I'd got with the Yoshi TRC Cabon, and yes, the '05 spec is the same for the '06 and YZ is the same as a WR...SC
