New owner of a F30 320i, I wanted to know if installing the 340i exhaust on my 320i would increase power? Also does it trigger any faults or problems?

1. I don't think it's possible without modification
2. No it won't add any power
3. No it wouldn't add a check engine light.

Just remap ECU and TCU to stage 2 and decat it , you will get the power you want , don't waste the money on the exhaust swap
