I am looking at the exhaust diagrams and see the pipe bolted to the turbo also has a cat in it? If that's clogged would I have the low 3-4 lbs boost? And no cel and no smoke or weird noises? That would kinda make sense to me as it would start to build boost then dump it out the wastegate....? Would I hear that? Or am I on the wrong track here? I put my infrared gun on the back cat. Didn't realize this was a cat as well. Looks like a pain to get off.....lol!
