Does it sound like a vaccum leak or an exhaust leak?
Do you have any way to scan the fuel trims?
Take a look at this elbow to see if it is cracked.

your going to have some added tap due to the stainless being thinner than the cast manifolds thats normal. some cars through rear cat codes due to them not heating quickly enough they will fix that with the tune
