Retune after going back to stock fatback?

Hey everyone. I have a full exhaust system with a dyno tune on the car and I want to go back to the stock catback system because the car is way too loud. Would I need to retune it if i chuck the stock catback back on the car?

Are you NA? If you're only changing from the cat back, I wouldn't worry too much.

Maybe log a bit if you're able, and make sure you're not suddenly seeing anything weird in terms of knock or timing being pulled.

If you said you were changing back to stock headers and frontpipe, I'd say definitely get it re-mapped.
If those parts are staying as is, or have been stock all along, your tune probably won't change much just by swapping out the cat back.

If you're forced induction, throw everything I said out the window - if you're changing your cat back on a turbo/SC tune, get it remapped/checked.

Are you changing the headers or FP? If all your doing is changing the Mid pipe and muffler no re-tune is needed.

Yeah just the midpipe and muffler will be going back to stock. I will be leaving the catless header, overpipe and high flow catted front pipe.

You golden then. No re-tune needed at all.
