I've been waiting on a ProMotoBillet insert ( recommended on http://www.thumperfaq.com ); yet to ship for the 05_WR.
Meanwhile, I've removed the restrictive (black) insert from the stock exhaust; makes a big difference in performance when done with the other "free mods" shown on thumperfaq.com.
Initially, I removed the entire silencer, but the bike sounded horrible -- thus, I removed the insert from the silencer (as shown on thumperfaq); now it sounds much better, quieter and I did not notice any performance loss.
Still; for $39 -- I'll try the promotobillet insert when it ships.

I use the GYTR baffle for a wr426, and I feeel it made a big power increase. I was actually looking for LESS power, but had to replace the stock unit (broke and lost). Good bang-for-the-buck, IMHO. K
I've heard that the stock exhaust is good when uncorked (rather than FMF / WB replacement - true or not???), and came across this insert which claims to provide a substantial power increase.... any thoughts guys?
