There are actually two resonators between the Downpipe and muffler, the first one is small and attached to a part of the exhaust that is large and oval shaped making it harder to work with. The second resonator (closer to the muffler) is the typical long cylinder style. That's the one I had them cut out and weld straight pipe in for $80. The results were best summed up by my girlfriend when she got in the car. "I thought you went and had your exhaust changed today?" A guy at the muffler shop asked if it got quieter. It's no big deal to me be needless to say, I wanted to let everyone know that there was no percieveable change. The wait continues for awe to come out with their solution...

Look at this video.
M Performance Exhaust with dual resonator delete. Pretty good i think.
Maybe the problem is that additional resonator BMW installed but you'll need the MPE.
