Downpipe noise

Question, I have a Lexus IS200t and installed a new catless downpipe. Now under load it sounds like there is a leak (like a small rattle sound). I have reseated, retightened the vband/midpipe connections and smoked the exhaust. There seems to be no leak, new gasket were installed and rechecked so I'm at a loss at this point. Has anyone experienced this?
