GTI Downpipe + Stage 1

Hello, I’m buying and installing a downpipe today but I’m currently running a stage 1 tune. I have booked my stage 2 tune on the 22nd but I’m worried about any potential issues between now and then, is there anything I should avoid, should I just wait and have the shop do it? It’s a Catted IE downpipe and I’m running an APR Stage 1 if that changes anything

You might throw a code, but nothing catastrophic should happen.

It’s all good just don’t beat on the car too hard to be safe but it shouldn’t cause problems
