My KM reminds me of the 69 Mustang I had before I sold it to repair another car and that mustang looked good, ran good, and was louder that shit, just like my KM. lol Heba diffusers are amazing because as my KM is soo damn loud I want to put a muffler on it.
I know heba diffusers work because I had one for my mya. works great. Keeps em silent and vibrationless. Although it pisses me off that they don't make em in metal because the plastic absorbs the nasty flavors and ruins the diffuser after about 6 months tops. I would easily pay over 20 bucks for a pure metal diffuser.
