Re-tune w/ new catback?

[efnfast]

04 that's ported/pullied/intake/catted X and magnaflow catback/tuned. Thinking of swapping to borla stingers just to do something different (but leaving the catted X). Would a new catback require a new tune, or probably close enough?

I don’t think so . I follow last couple post where other asking same question . None I saw that require retune after new CB .

Na you’ll be good. I’ve swapped catbacks plenty of times and doesn’t change anything other than the sound.
