Need some help
Hi everyone, I'm new to the forum and realize I have a ton to learn about my car. I just got a 2011 335d and have some questions so if you could help me out or tell me where to go sinceIim not familiar with this forum yet thatd be great. I know it seems its not deisrable by most but id like to get more whistle out of my car and also if anyone is able to get black smoke out of theres how can I go about doing that? I know you can unplug the turbos but I dont really wanna do anything that will affect the pick up of it and also cant do anything that would void the warranty since it has a 100k warranty on it. Thanks in advance
