yz pipe louder than stock(baffle out) yz silencer fit on stock header
I have to disagree here. I'm running a YZ exhaust with a PMB end cap and it is significantly quieter than the stocker without the core. It is definitely not 96db (probably closer to 100). The numbers I've seen show the stock open can at around 103db. And yes the headpipe is the same on YZ/WR.

'05 pipe has been redesigned and is now at 96db with the restrictor removed.

Ya, the '04 and older pipes are insane uncorked.

Two ways to go (for the moment).
Is it possible to 'uncork' the '05 pipe on the WR I noticed it looks a lot different than the '04.
You can drill out the two rivets and pull the plug as shown in www.thumperfaq.com
This keeps it at 96db.
You can remove the entire tailpiece and put the cone back on.... it's louder, but I don't know HOW much louder.
ProMotoBillet is finalizing a replacement tailpiece with a larger opening than the unplugged stocker. Knowing them, it will flow better than the unplugged stock pipe and be just as quiet.
