I have an original Stebro exhaust. Fits all Z4 (non-M), 2003 - 2008. Installed and used for about 1k miles, and now back off the car. Retail $675, I paid just shy of $500 for it. Reason for selling: I would like to get something louder. This exhaust is still clean and the tips are gleaming. Wonderful sound down low, and doesn't develop too much louder than stock at WOT.
