Defowler needed?

[Vtec Joe]

new to k series.. was looking at downpipes and seeing defowlers for o2 being sold separately.. Is a defowler needed if you are running flashpro? I'm leaning toward the full race cat-less 3in downpipe.

no not needed but for inspection reasons you will need it. I have the full race Catless dp and only use it for the state inspection and then I take it off.

If you ever want to go back to stock it will likely keep the o2 from being damaged. If you don't care about that, flashpro can disable the o2 check engine light.
