Got CBE coming...considering test pipes and the drop ins you recommended. At what point do u require a tune? (Car doesn't have 2k miles on it yet, so warranty considerations). Also, I've seen folks who have test pipes and the have the check engine light on....does this always happen with test pipes? And with test pipes, my state requires an inspection....guessing I would need to see a shop that understands the Z so I don't fail. Am I off the mark?
