Wastegate Clink

Just had the Maddad midpipe installed ( stock downpipe & PE ) and when lifting off the throttle there is now a metallic clinking sound. Coming from the area of the wastegate and assume this is what it is. My guess is that the secondary cats created back pressure that dampened the waste gate movement. Anyone else experience this?
