Can anyone tell me what is a good pipe and silencer for a 04' KFX400? Thanks for any advice!

 

Run the HMF sport series or the Ballance series. Bewarned, HMF is loud, but it s great. If you prefer quiet, run a Yoshi(great pipe also). Just depends on your riding.

 

I have a White Bro's E series (with the adjustable fins) slip on on my 04 400 kawi. I love the sound of it. It's pretty loud as well, but any pipe you put on there will def louden it up to a certain extent compared to the stock muffler.

I've never really payed attention to the silencers out there because I like mine loud, but silencers should help somewhat.

Powerwise....my bike came with the slip-on...on it. But when I put my Pipe on my Mojave, I really didn't notice that big of a difference powerwise. The noise alone makes you think it's faster, but you really have to do extra mods along with the exhaust to notice anything.
