I see no justification for charging almost three grand for this. Only thing I see is someone trying to bump up the "M" Tax to a whole new level. That is a sub $1k shipped product. SS even... c'mon... pricks.
EDIT: You know, if exhaust manufacturers would get their heads out of their asses and realize that if you make a product like this, charge a low price instead of that crap, then people that drive cars like the M3 would buy it JUST to put it on and play around with it for a few days or at a track event or whatever, then remove it and use it later/sell/trash, whatever. Generally speaking, YES, most M owners have the cash, but take advantage of it in a different manner... Sell this for cheap, draw a crowd to your business increasing word of mouth in the community, then sell the pricey good quality stuff to the customers you drew in with this "toy"... simple.
