I have been searching for a while and haven't found exactly what i am looking for. I need to know if there is a company that makes CARB legal High Flow Catted down pipes. From the search I have done below are the three options that i am looking at. I would really like to know the thoughts of the community. The car in question is a 2007 335i n54 E92 and currently has catless down pipes and I need to make her legal again but with an eye on performance. I also added a stock set off of ebay strictly for a price point perspective.
