I am not sold on White bros. pipes, my friend has the full pro meg system on his 300EX and my other friend has a stock 300EX and I had a 250X with a slip on PC pipe. Both the stock EX and my X seemed to have more power through out the entire RPM range. The white bros. pipe just seemed to be pretty loud and not that much power. ALSO he has a K+N filter and it's properly jetted too so I don't know I just don't like white bros. I think the PC pipe is excellent, I know this is for a 400EX but I just thought I would share my experiences.

I have an E-series on my 400EX with 18 discs and a 165 main. In drag races with friends I can beat my friends EX with a Pro Circuit T4 and pull dead even with another friends stock Banshee.
Combo: No airbox lid
165 main jet
42 pilot jet
Needle moved up one position
White Bros. filter
E-series 18 discs
Also it's not anywhere near as loud as the T4 system.
