The only issue I have with manifold is I having trouble controlling boost, might not be related to the manifold I'm just after some help, I can take some pics tomorrow and update my phone so I can upload pics to SAU, exhaust setup is 3inch pipe welded to 3 inch dump v band on 45 degree decline down to the bottom of the firewall then flagged joined there to 3 inch pipe with 2 mandrell bends into cannon no muffler no cat, I cut the 2 bolt wastegate flange off the manifold and welded the tial v band on then fitted the 38mm gate to that then from the outlet of the gate a 90 degree butweld and a pipe 150mm long screamer, and the line to waste gate comes out of the inltet manifold down the back of the head to the wastegate 6mm internal diameter line
