2003 Honda 400EX(Red) what upgrades should i get first?

 

Fusion,
I owend 2 400exs the 1st thing is a pipe. I ran WB e-searies. then a K-N jet kit. I was told that unles your going big bore/ cams the stock head pipe was very good, so I stuck with the slip on. hope this helps!! [img]i/expressions/face-icon-small-smile.gif[/img]
any good riding areas in your area??

 

how much money do you want to spend?
get the full system whatever you get, not just the slipon.
then get a uni, of kn filter, and jet it......
dont go with white brothers there are many good pipes out there
sparks, LRD, MBRP, yoshi......those are just a few of the good ones.

 

I say just get the slip on and filter with outwear then you can run with the lid to your airbox off. Rejet and you're done

 

1) Full chassis and swingarm skid plates, nerf bars, and bumper.
2) Tires (sometimes the stockers hold up, and sometimes they don't).
3) K&N/Outerwears, FMF Powerbomb Header and TI-4 Muffler, vent the airbox lid (unless you ride in a lot of water).
4) Aftermarket suspension someday when you can afford it.

 

i dont agree with purchasing the fmf pipe...i dont know much about their header, but i do know that i havent seen anything good come from the fmf pipes......
