Hey people Iam looking for a pipe for around 250 for my 400ex. I was woundering how the FMF Power Core IV Q Silencer is and what all i need to get with that? Or should i go with the FMF Megamax II Exhaust? Is all i need to add with the pipe is a K&n airfilter or what? Please let me know everything i need to know what this stuff all suggestions iam open to. Thank you very much my fellow riders.[img]i/expressions/face-icon-small-happy.gif[/img]

 

my buddy has a 2000 400ex with a procircit t4 ,uni filter and 155 main jet that thing rips for a 400 cost arround 300

 

My buddy went with a White Brothers E-Series pipe and a jet kit w/ a K&N filter and that thing hauls a$$.[img]i/expressions/face-icon-small-happy.gif[/img]

 

True but he only wants to spend 250-300

 

Do i need to get a jet kit? I was thinking just the pipe and the k&n air filter. FMF Power Core IV Q Silencer is this a good pipe you think?

 

No a jet kit is basiclly a waiste of money. Id just go to your dealer and ask them what size of jet you need. Instead of spending $40 or so on a bunch of differnt sizes you wont need. Spend $4 on the one youn need

 

I like the HMF pipe I have a R-4 now but it came with the quad.. And Im going back to the HMF...They will hook you up with the jet you need according to your location and I believe there only $209 for a slip-on They come in alot of different colors and look and sound great not to mention perform Awesome....HMFengineering.com

 

i agree with italianstallion. my frien has a white bros e series and k&n and his quad is quick. that would be my choice

 

For most people, the FMF will sound much better than the E-series and also will perform about the same. Do not buy a jet kit. You will only need a little bigger main jet ($3), depending on your other mods.

 

Try DG Xccelerator Stage 3. You get the whole system with out spark arrestor for around $275.00.
