Hi I am new to BMW Fanatics, I currently have an F30 320D. Recently I have done a few modifications to the car which includes fitment of a DP and software. This has significantly improved the car's performance. I am now looking at making further performance upgrades as this is addictive, I am going to complete the exhaust and I am considering fitting an intake - not sure? What are your thoughts around modifying this car and what options do I have?
