I just had my 320i done at Powerflow in Salt River, awesome service and great results. Cut all 4 out and fitted 2 resonators where the bottom cats used to be. If you dont fit those resonators you will get a more tinny sound when putting foot which i didnt really want, i prefer to deep note it makes. Full freeflow will cost you some cause it is dual pipes all the way from the engine to the back. If you are in the cape try give Gerrard a call at Powerflow 0214481325.
