Not had the car that long and I'm chasing a rough idle misfire with no codes being thrown out. I'm sure I can hear a major hissing noise from down behind and under the egr valve(not sure if that's normal) but I cant locate any leaks at all. I took a video of the area today to check for damage and the exhaust manifold doesn't seem correctly installed onto the second section of exhaust.

I have attached 2 images of both sides and there's a huge difference! Didn't try to tighten it up incase I damaged it with the weight of the exhaust attached.

Thanks in advance!
