I don't think you'll see any gains with a 328i quite honestly. Some have actually reported a decrease in hp that came with the decreased back pressure. What are you going to do with the cats?
Most leave the muffler and delete the resonator. I'm curious what you think of the sound and the volume with your straight pipes. Too loud?
