In Reply To External Wastegate Dump, SZ Downpipes... possible? posted by gsrteg on September 30, 2013 at 05:43 PM
     
Message The hourglass like shaped block that gets installed with the downpipes to separate the waistgate and exhaust sides of the turbine outlet is not a perfect seal. Even when you were idling around not on boost (i.e. waistgate is closed) I bet you would hear exhaust leaking past that block and out the cut off tube.
