hey guys,

I want to change my OEM exhaust on my 640d. I saw this guys YT videos https://www.youtube.com/@vasylpopovych2796/shorts. His car sounds incredible to me for a diesel with minimal smoke. I really dont want my car to smoke so ideally i would do set up like his but he just said he changed downpipe and rear muffler delete. I would appreciate it very much if anyone has experience with this engine or diesels in general could help me how to achieve this.
