Issue with vibrations on Sheepy manifold
 

I am in the process of fitting a put together kit using a sheepy T4 manifold, 6262, and tial wastegate. The issue im having is the vibrations that show at the wastegate around 3k...it vibrates like hell and has the sound to match. I've searched the forum and saw vibrations are common with some front mount kits but no one has ever had the problem with sheepy's manifolds. I'm going to have the dump recirculated and im sure that will help stabilize the wastegate some but does anyone have any recommendations?

Fix a bracket that will hold the wastegate dump tube... or connect the dump tube to the downpipe with a small flexible piece in between. Otherwise it'll probably crack
