Tune and Downpipe question
For starters, I am very new to BMW/tuning so please forgive any naive questions. I am looking to potentially tune and add a downpipe on 2020 M340i xdrive. I put a decent amount of miles on per year (20k) and wondering if that should change thought process of adding tune to vehicle. I am looking into doing Carbahn stage 1 tune with downpipe. I havent seen any feedback reviews with Carbahn tune, and would be interested to hear thoughts on this?
Also if I got downpipe without tune, what would expected horsepower/torque gain be? I currently have Dinan exhaust and am thinking about adding intake when one is available. Any thoughts and feedback would be helpful |

Are you liking your Dinan exhaust so far? I'm having mine installed this month

Thanks chenry, ill do some digging and see what i could find.
Love the Dinan exhaust, stays relatively quite in comfort but sounds great in Sports Plus. I have black sapphire exterior with black tips and looks great, I got back when it was first released and it shipped right away |

I'm getting the Carbahn tune Tues. It's not as well know as BM3, MHD or Mission but based on things I've read on forums and facebook user groups it seems its popularity and use is rapidly growing. I've read about and/or IM'ed 5-6 guys that have it and all love it.
