What are your thoughts on this subject? Do you think its a waste of manifold design & construction to use a single wastegate on a twin scroll manifold? By single wastegate I mean the merging of a tube off each collector together into the gate.

 

I`ve seen that beeing dune before...

 

It could be a waste If not done correctly

 

Works fine. We have done it before with good results. The 2 pipes were seperate until they entered the gate
