2005 400EX Exhaust

[GenZC]

I'm new to the ATV world i seen some kids on a track racing with loud Exhaust seemed to make them zip along faster. i was wondering whats a good Exhaust for track and trails. i know on trails it can't be loud so can someone please help me out?

there are alot of different pipes out there. it depends on what kind of power your looking for and how much your willing to spend. and alot of companies sell spark arrestors with their pipe if you want something a little quitier.:)

i know its loud, but Sparks racing all the way, the X6 in my honest opinion is far better then any other pipe (these are basically equal to it) LRD, trinity, and HMF, but i like the sparks look, i rode a 400ex with a full yoshi and for the price it stuck out a rediclious amount past the grabber, and didnt have the punch mine did.
