WR400 and E series pipe

Anyone run the White Borther's E series muffler/pipe on the 99 WR or YZ 400? Do you need to do any jetting or other changes after putting this on? I have the opportunity to buy one and was curious as to what it would do for me and also what a good price would be. Thanks

I'm running one on my '00 WR400, but it came with the bike. I can't honestly say what difference it makes as far as power, but it does sound good :thumb:

I was also interested in jetting for it. James Dean makes some nice jetting kits. What jetting and altitude are you running wrfrk.

a454elk,
My friend had one on his 98 YZ400.
When compared to the stock pipe, the E-series seemed to give a decent increase in mid-top end pull with plenty of torque still on tap down low.
The only downside to the pipe was the (I felt) excessive noise, even with the S/A installed.
