When Craig bolted on the downpipes, they touched the underfloor. They will have to be cut and re-welded to slightly correct their angle, not ideal being ceramic coated but the only way. AAM used a test rig to align exhaust parts, which may have introduced some variability.
The fuel line routed past the turbo housing within a few cm, which H-Dev fortunately identified as a disaster waiting to happen, and thus, added a thermal barrier blanket, bolted to the chassis side wall.
This photo shows the boost solenoid of my GReddy EBC kit. It is being*mounted centrally behind the plenum such that the vacuum lines are of identical length and as short as possible.
The downpipes adjustment is the last major mod and the remainder will be finishing work, electronics, CMC and such.
