HMF pipes are fairly loud but they are also one of the best pipes for your money. We run them on a KFX700 (duals), a Baja X, and two KFX400s. Wouldn't trade them for anything. Awesome custom support too. Call Joe at HMF Engineering and tell him that Matt Smith referred you. He will discuss with you all your options and recommend appropriate jetting for his pipe with the airbox setup you plan on. Be sure and tell him I sent you and help me out.
