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?

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. |

I agree Tune should be OK.
