Re: 400 EX header pipe and silencer?
hey...i have a 400ex too and your having the same problem im having..if it helps im leaning towards the duncan fatboy4 complete exhaust system which costs about $550 or maybe even the FMF factory4 with connector pipes and power bomb which is a litte bit mor expensive around $600. you might also want to look at lrd or hmf pipes b/c of the lower prices and are suppose to have good exhaust systems.
if you get an exhuast tell me which one and how much you like it. thanx
