1) It is a federal crime to tamper with the emission control system (they have to catch you right?, not a big deal)
2) If a primary cat dies (which is not an uncommon issue on M cars), BMW will not give you a new one under the original 80K miles emission control warranty, which means you're buying a new mid section for 3K if you plan to sell the car without being in theoretical legal pickle.
Just my .02
Would be nice if BMW made the center section in 2 pieces.
