External wastegates & screamer setups

[s13eater]

you need the screamer flange onto the collector, or if theres no room to get the wastegate in there, then a pipe into the collector, then put the flange in a seperate place.

i just use the wastegate straight onto the manifold collector and dont use a screamer pipe. The external wastegate just dumps to atmosphere. I wouldnt ever go back to a normal internal wastegate again.
