Downpipe OEM Re-Tuning Required?

[k0bryant]

Tuning Question: I installed a catless downpipe, and used a Hondata tune to accommodate the downpipe including disabling the O2 sensor. I am switching back to the stock downpipe, but left my Hondata somewhere else. If I install the OEM downpipe, will I be able to drive the car?

I’m guessing here but yes. The issue will be more related to emissions testing but not sure that’s a thing in Florida.

Yeah - I'm most concerned about engine timings and all of that being affected by the change in the downpipe, and if that will throw some kind of warning or make the car undriveable until I can get it reflashed.

Yeah you can drive it, just not hard and avoid going into boost if you can
