its the exhaust back pressure valve doing that, sounds like ass too. Its a butterfly type valve in the exhaust and is supposed to restrict the exhaust to help it warm up faster. Mine warms up the same no matter what and I have mine unplugged, I have noticed any difference except the noise is gone now.
