328i 2009
I have a 2009 328i and I recently had my muffler removed replaced with straight pipes and a injen shirt ram intake installed by Andrew from activeautowreck. They did a great job. My car has a tremendous improvement in sound and airflow. If you drive the car on a daily bases you can really feel the difference. I'm waiting on the development of headers and then I am going to get the AA tune, heard alot of good things. If you have any other suggestions feel free to comment. Hopefully the supercharger comes soon!!
