Just got a new 400ex about 2 months ago and can't deside what slip on pipe I need.
I want one that is pretty loud with good power gains too
I don't want to spend over $250
anyone that can help, thanks

 

Trust me on this and save your money until you can afford the LTE dual exhaust. My friend got it and it made major differences. It feels more like a 450 now (yes I have ridden both) and it sounds great. It's expensive at $670.00 but well worth it. Check it out at lteracing.com. It even comes with an aluminum air box that you relocate the battery into (no more hanging out in the open to get ripped off) and has all wires etc. with it. The only thing you will need is an aftermarket air filter which you would need anyway. Good luck.

 

hmf is probably a good choice also loud and good power gains

 

where on the net is a good place to get a hmf
i planned on ordering from moto-man.com but they don't sell hfm

is fmf megamax slip-on a good pipe? i thought about getting one of them but i have never heard one

all my friends that have a pipe have got cobras they are really loud.
one of my friends said he would sell me his cobra for $10 any pipe should be worth that much
i don't know if they add much power though but they are loud

cain73, did the 400 with the lte pipes have any other mods??

 

the Yoshimura we put on our 400ex gave a big noticable power increase

 

www.motojoe.com sells hmf and yes yoshimura is also a great pick

 

i went to motojoe.com and i think i will order the hmf kit
it includes slip-on muffler, k&n filter, and spitfire plug for 245 dollars

Do you think i will need to get the dyno jet kit too?
if i don't really need it i don't want to buy it too its an extra 55 dollars

 

if the hmf kit does'nt come with jets. get a jet kit and just follow the directions for the parts your running and elevation . cant go wrong.
