What is the best exaust for a 400ex.

 

In my opinion id go with a Duncan Racing Fat Boy 4.

I heard tat CT racing makes a good exhast system for the 400. You also might want to look into the graydon proline exhaust system.[img]i/expressions/face-icon-small-wink.gif[/img]

 

for the money i would say hmf slip on its only 220 there web site is hmfengineering.com. I had a full yosh before and the hmf slip i think has the same amount of power and looks better i have the red one you can also get them in many colors

 

I had some people telling me that a white brothers e-series is the only way to go...what do yall think about that exaust

 

White bros E-series, DMC, or Curtis Sparks!

 

Big gun!

 

Two words " Curtis Sparks " Dont think about any other pipe. They are awsome. They add gobs of torque, A hard hitting mid range and great top end. They sound great too. Go to www.sparksracing.com and check them out. You won't be dissapointed.
