You want your gate in the main exhaust flow, witht he least restrictive path.

 

The Ba/bf turbo manifold flange is a dick of a spot.

 

The fg manifold has a nice merge and spot to weld in a external wastegate, but to correctly follow exhaust flow (90deg or less angle from flow) the gate ends up close to turbine housing and heat...if you weld it on a backwards angle, more than 90 degs it sits way nicer but you may run into flow issues.

 

My ba has a J pipe for the turbo and the wast gate is right on the bend of the J pipe, right in the exhaust flow has perfect boost control.

 

the modified exhaust housings have a bend and the gate sitting away from the turbo, this does work, but ones again you want that gate right in the exhaust flow, ideally you want that gate right on the exhaust housing....but its not practical with the falcon.
