External wastegate on MSM manifold
My MSM boost creeps when i am catless. Im wondering can i weld on a external wastegate on the stock manifold and turbo, weld the internal wastegate closed and not have boost creep?

I would just dump it to atmosphere, and i wasn't planning on changing the turbo until a couple of years down the road so no point in a new manifold. Im just wonder would this solve my creep problem.

It will be even worse having the dump pipe go to atmo!
You need to smooth out/taper toward the wastegate hole so air is encouraged to take that path. With it stock it has to take a 90 degree bend pretty much.
I've attached a pic of my MSM turbine housing to show you how pathetic it is when stock.

Reading on the interwebs that if done right it will hold. Heating the manifold up then Patched it back up with ye old metal caulking gun let it slowly cool down
