I am planning on putting a catless downpipe on my 2017 honda civic hatchback sport, and I was wondering if I can get away without tuning it in? I do plan on getting a tune eventually but was wondering if I would need to immediately. Given that the o2 sensor is on the downpipe I am sure i'll be running all sorts of engine codes related to o2 monitoring. Anybody have any experience with this? Advice?

My advise would be not to until you can adjust for it.

Fabspeed O2 spacer. It has a mini catalytic converter built into it to filter out the fumes before they hit the O2 sensor.

Yes, you could get away with it.

Your check engine light may come on. Also, your turbo will spool up quickly and your low down torque spike will be 'uncontrolled'.
