Which exaust should I get for my 2000 400EX?? I'm thinking one of the following: DG, Big Gun, FMF and White Bros. The Big Gun might be a little loud for my taste. Anyway, any info/help would be appreciated. Thanks, Drew

I just got a 2000 400ex about a month ago and wasn't sure which exhaust to get for mine. My buddy has the Big Gun which is Sweet, but in my opinion it actually robbed a little from the low and put it in the middle. Anyway I bought the DMC Dual exhaust system which has straight exhaust pipes back to the silencer, instead of the two into one like all the others. Anyway I put the system on, added a K&N filter, and jetted it to a 158 main jet just like my friend's. We raced and MINE WON!! When u get your system, no matter which one put some holes in the air box lid.. if u don't you'll have to put a smaller main jet in when u jet it. There's also a new system out that looks pretty FAT. The titanium Yoshimura system. Call Duncan racing and talk to them. That's where i got mine from. Good luck..
