hmf is known for their good sound, and low end punch. i havent heard one on a yfz, but its pretty deep on my 400. same thing with yoshi, havent heard on a yfz but ive heard one on a 400ex, and the hmf sounds deeper

The HMF is a beautiful/bad *** sounding pipe on a YFZ. The Db's on a HMF w/ the 450 is around 102-104 w/out quietcore......w/ the quietcore in it throws it down to 94-96
