well i finally decided to go with the complete hmf system. i stayed with just the aluminum version didnt think the red or black would look that good. but anyway i ordered it last monday so it should be here in a couple of more days. just thought i might share, but i will tell yall how it does when i get everything on.

 

Cool

 

i got mine in the standard aluminum finish too. It looks awesome on my yellow 400ex. the head pipe gets discolored very quickly though. Pretty loud, but you notice a big power gain. only run a quiet core/spark arrestor when you really need to as it is very restrictive. Great choice
