400EX full pipe shootout FINALLY!!!
#1
The latest issue of ATV Sport has a shoot-out of a bunch of pipes for the 400EX! Mostly full pipes but they tested some slip on silencers too. Over 16 different pipes were tested on a new 400EX with jetting specified by the pipe manufacturer. Testing was done with a DynoJet Dyno and a Stalker radar gun used in conjunction with acceleration testing software.
