A few months ago I purchased a 2023 BG M240i x drive and I love the car. However it’s time to start modding. So far I’ve got a milltek catback exhaust and an AA downpipe on order with plans to purchase a dinan CAI in the near future as well.
My question is are all of these parts safe to put on without tuning the car first or does it require a tune to be safe? To be clear I understand I probably won’t make any performance gains with these parts alone I decided to start with making the car sound good first before focusing on performance. I’m kinda new into car modding in general so any advice or tips you have are welcome thank you.

You are perfectly fine to put those parts on the car without a tune. There are lots of people on this forum who have added those.

Also you are wrong you won’t get any performance gains without a tune. You almost certainly will.

Definitely will see gains just not as much as you will if it’s got a good tune

If you're not sure what tuning option you want, I'd highly recommend the JB+. It's cheap, easy to install, and very effective while staying safe.
