So I installed my aftermarket head (OBX) and the Dcat. Everything lines up fine and the quality is great for the low price. The only knock I have so far is that the bolts and springs to be used at this flange are too short. I checked out a few other aftermarket suppliers and they use solid joints at this point. Will this not eventually crack? I know these cars have alot of engine rotation. What takes up that movement? The muffler mounts?
