if you dont mind me asking, why pay more for an exhaust that says BMW on it than any other exhaust on the market? at the end of the day, you've still got a round pipe, with a muffler and resonator that makes more noise than a stock e90. any other company can make that for less money and probably produce slightly more gains being mandrel bent.
the BMW fanboy fetish doesn't make sense to me. you'd rather pay more for the same product?
