Hey i just got back into riding again. I went with the 400ex dude to the trail riding I do, and the jumps i love hiting. Im looking to gain alittle more speed and power while keeping it a good trail riding quad.
Its a 08 white 400ex, and so far I have only bought a pair of black AC nurfbars. I'm looking to pipe it out and other opinions you may have gaining a little more speed.

What pipes out there sound good and run the best. Mainly i been sticking to youtube to check out the sounds of a few.
Thanks for the help fellas.

get a full yoshi

A full yoshi is going to cost a pretty penny for just to sound good. Look around for a fmf PC4, friend had one and sounded great.(maybe a little loud though)
