Just wanted to quote this and say thanks, you were dead correct. The smoke hasn’t returned.
Just again want to thank CV and guys like yourself who constructively helped and guided me. It’s always a satisfying feeling to fix the car yourself and not pay a mechanic to do it ;D
The only remaining item is to adjust the exhaust so the tips don’t hit the valence. I used the center connecting bracket to translate the left tips to the right, which in turn moved the right tips to the left. I probably need to go further upstream to correct the alignment. They aren’t hitting the valence normally, but there is pretty much no clearance. Definitely wish I had smaller tips.
I think my passenger side exhaust manifold is cracked. Waiting to hear back from the shop. I have the Milltek cat-back, non-resonated. It’s unclear if my shop cracked it while installing the motor mounts.
