I whent to my local dealer and asked the cost on a slip on pipe for my kfx 400. He said that to get a full system is pointless because all the aftermarket head pipe does is creat more noise. Personally i believe he might be full of you know what. Something i noticed though was that everywhere i look the HMF slip on was a lot cheeper than any other system. Does the HMF just not put out the same power or are they just priced more fairly. Thanks guys.

 

well i always thought they put out some great power....

 

Oh, the HMF is a great pipe, well it is for the predator!

 

thats what i hear, it usually gets in the top 5 at least into all the pipe shoot outs the magazines have.

 

The head pipe does matter if it is a larger diameter than your stock one. Also, it may be made from a slightly lighter(weight) material.
