If sound is not a Problem get a Engine Builders Pipe. I think they are Better.

Get a WB I'm tellin you I put one on mine and I got 7 horsepower out of it so do what I did go with a White Brothers E-series pro meg complete. :huh

I doubt you got 7hp just from exhaust. You can't believe what the magazines claim. Have you dyno'ed the quad since the install?

I believe Tom Carlson builds everything for low & mid power, so you might try one of his pipes. I really like the Big Gun, but it is more of a mid to top pipe.

[Dave400ex]

Yeah everything Tom makes is for Torque. If you Call and ask all he talks about is Torque. I can`t Wait to Order a Piston and Cam from Tom.

I have had both the Wb and the Yoshi and they are both really good but the yoshi is my favorite.

My one friend has a Yoshimura pipe on his 400EX and it sounds good! I never rode it before he had the pipe on, so I don't know how much it help in the power department.

You could Try the New Duncan Fatboy too.
