However, Railgun is right - the state of California doesn't do emissions tests on new cars - only after a car is four years old. I also suspect, unless it looks homemade, that your typical smog station attendant wouldn't be able to pick out an aftermarket exhaust unless it was really loud (which I don't want - just enough so that I can actually hear the thing).
But, back to my original question - anybody know what the cat-back portion of the exhaust weighs?

Richard,

According to UR, the factory is 78lbs and theirs is 55lbs. Also, the 330i muffler is about 30 lbs if that helps any.
Good luck!
