getting ready to pipe my kfx 400, just wandering if anyone out there has any suggestions.

 

heck, I wouldn't waste the money.... they're all too loud anyways...

just remove the spark-arrestor and the smallest baffle or quiet core pipe you see

switch to a K&N air filter, and upsize your main jet

who are you trying to beat anyways???? you could beat EX's stock, but you're not going to touch a Cannondale, Predator, DS, or Raptor with bolt-ons... that's why if I owned a KFX or Z... I wouldn't waste my money on a full exhaust system.... maybe a used slip-on from EBAY if you can get it cheap

 

one should recognize that he might have a buddy w/ a kfx400 that he wants to feed roost [img]i/expressions/face-icon-small-happy.gif[/img] Thats why i built my mojave bad a$$, cause it was the fastest 4-stroke 250 around.
My local dealer put a Yoshi slip-on to the first one delivered to him. I rode it and it wasn't terribly loud. Just make sure and jet accordingly to get the most bang out of your buck.

 

Pump up your machine anyway you can...make it as fast as you can...Smoke as many as you can...

 

WB , ProCircuit , or CT racing I have put all three on my KFX and decided to keep the CT I like the sound better then the WB , but the Pro Circuit seems to have given me more power

 

i got the fmf titantium 4 it made a world of diference.it sounds deep to.

 

ct sonic, or a hmf

 

I went witht the Muzzy pipe for my KFX...I talked to a bunch of guys around were I live that also have the KFX and that's pretty much what they were all running. The pipe looks awesome and doesn't cost a great deal.

What other pipes have you heard on a KFX? What is the Muzzy comparable to as far as sound pitch and loudness. Thanks!!

 

The Muzzy pipe has a nice rumble to it but it's not TOO loud...The HMF for example is a nice pipe give good power increase but is really loud! I'd have to say the Muzzy pipe sounds kind of like the Yoshi pipe as far as pitch goes. Muzzy is to Kawasaki as Yoshi is to Suzuki....Kind of R&D type deal I guess. For the price of the Muzzy pipe man you can't beat it...I bought the pipe and the jet kit for $253
