What kind of budget are you working with? There are a lot of great brands...

around a couple hundred the 250 needs a little bit more pep

Check out HMF. I have heard many and they sound good on all and people say they perform great.

Yea Hmf's are $250 for slip-ons and thats brand new. But if your patient you could find a slightly used one for that same price Full. I'm sure you know of Atvriders.com/exriders.com? All of guys there are selling stuff.

Also check out a two bros racing pipe I heard a slip on on a 400 once and I loved it!

Why dont they make a full sys for a 400ex. I wish them or Dasa made a full for it then I would go buy one.

Probably not cost effective. The 400 has dual exhaust ports, that would be that much more money that they would have to charge for the additional header pipe. Any aftermarket header that supplies more flow will fit on a 2 bros. mid pipe.

Is jetting a pain with a set up like a fmf header and a 2 bros mid? I heard thier was a program to calculate a ll that mess but I dont know. I will probly buy a Curtis Sparks. I bought one for my 450r and it was A nice pipe.. But Everybody around here has a sparks so I wanted to be diff thats why I dont have a HMF. Love the way they sound but its so METOO!

Jetting is a trial and error process. See what 2 bros would recommend for jetting with their pipe and probably go a bit richer.
