where i could purchase a HMF header only, Can't seem to find but full system or slip on. Or anyone know for a fact what header fits an HMF slip on, on a KFX400. thanks

i think on a 400ex and a yfz, the fmf header will work with a different slip on...so maybe call them and see if it will for your bike.
