I saw this pipe on another members Hobbit and thought it was nice looking and they said it was also quiet. Mine had a Proma circuit pipe, which will wake the dead even though I heat wrapped it, so I asked him about making me one and he followed through and sent me this. I cant say enough about how cool he is and how awesome this pipe is on the Hobbit.- it is sooo quiet now that I no longer scare women and children when riding in the neighborhood.
