Re: Best Beef-ups for 400EX
I have to agree with the Uni dual stage foam users. It offers more protecton from dust particles. I think it does not flow as well, but like Airborn said, take protection for a long engine life before negligeable power for a short engine life. In fact, i run an outerwear on top of my dual foam Toomey 2:1 intake on my Banshee.
I think Dirtwheels had a pipe shootout a month ago for 400ex.
