It seems like White Bros Pro Meg system has won alomst every 400ex pipe shootout. It's one of the best pipes for the 400ex. Go for it.

 

it all depends if you want a slip on or a complete system. if you just want a slip on you probally won't notice much difference between brands. as for the complete system, yes the wb with promeg headers does produce good power. but if i was doing it i would be getting a race company pipe such as curtis sparks or lrd for example.
