So anybody know if the Whites Brothers E-Series Aluminum Silencer is any good for 04 EX400. And will that silencer connect to stock head pipe. Thanks!!!


"With that do u have to change jetting and do they break off easy or is that a myth"

alot of people do not care for the e series i have a hmf slip on and i love it

and yes the silencer or slip on will be clamped onto the header

yes u need to change the jetting if you want ur quad to run right u better jet it if u dont give **** about ur quad then dont jet it then ur quad would run lean and that is not good at all you probablly back fire, dead spots

What kind of slip on did u get from HMF. And what color and everything. how'd u order

[Ridin' Jesse]

get the sports series, and you can pick w/e color u want..look on the site.. http://www.hmfengineering.com

the e series are good exhausts, produce good power, i have one on mine... the only bad complaints from everyone is that the mounting brackets crack on the can... a novice guy witha tig welder can fix that up quick.. but just my 2 cents

hmf's are awesome also, get one of those!

yes youll need to rejett, main jet and should up the pilot, easy stuff though
