Another happy megan header owner here. Installed them myself. Was perfect fit. Clears FCAB, all bungs are in proper places, lines up with section 1. Couple years and no cracks I can detect, welds look good. Running Epic tune and engine seems quite very happy. Not sure how much power its putting down but I also have AFE dry filter in stock box, m3 intake elbow and RPI mufflers + air scoop.
One thing to note though. Do not use the included manifold gaskets! Buy genuine bmw.
