Im looking for a pipe and since the low end of the KFX isnt the greatest i want some low end have any sugjestions

 

Check out, www.hmfengineering.com

 

also take a look at www.ctracing.com, this is the pipe I am probably going to get or the procircuit t4, both should give you a better low end.

 

My friends all are running the White Brothers R4 slip on. It works great and looks good too!

 

My e-series race system has awsome low to mid. Took care of the soft low end and pulls pretty good on top. not a good system to have if sound is a problem though. I've heard CT also has a good system, do a search for it in the suzuki forum, theres a ton of old posts reguarding this topic.

 

I have CT, It gives little low end and then hits pretty hard mid range and pulls up to the rev limiter.
I am very happy with my pipe. Looks, performs, fits, and sounds good(not to loud).

In march 03 dirt wheels did a pipe shootout, CT and pro circuit ranked at the top. They also liked both white bros pipes. All pipes were with in 1 hp at 4000rpms, CT gave the most over all.

Could run a smaller front sprocket, or larger rear sprocket for low end.

Another thing you could try is remove the airbox lid and run a bigger main jet(155). This was my first mod and ou could feel an improvement in performance.

 

hey Lt, I bought an LRD pipe from K&K racing , They sent me a 160 jet with the pipe, that realy woke it up but by the time i put the air adapt and the uni I had a high rev spudder. the pipe is great - sounds excelent.Witi replied to my thread sugesting to much jet. So I went to see the boyz at andretti's for a 150 or 155. They said no try this 185- I did that and its good. I dont think the front tires have touched the ground yet!!!!If your bike is green buy the black ceramic it would look great. I got the chrome one - it looks good but wish ihad the black. The KFX loves the dirt !!!! cant wait to see the 450kfx. the wife will kill me.Good Luck. (watch those stupid carb screws their like butter- had to take some off with avice grip)

 

you might want to overlook the other suggestions and go straight to yoshimura.they are zuzukis performance line pipes.they are made specificaly for the kfx,z 400.mine works awsome all the way thruogh the powerban.fmf also is agood choice.

 

Does not mean that yoshi is the best for him. They are not bad pipes, but they are very loud.

 

try dgperf.com get the xcellarator with a 135 main jet gives good low end sounds awesome
