Secondary catalytic bypass pipes More power and rich sportscar sound for all Boxsters built from 2000-2004. (not compatible with Boxsters from 1997-1999) Note that the Boxster comes with two sets of catalytic converters, and only one set is necessary to pass emmissions tests - the secondary set robs your Boxster of performance through exhaust outflow, and muffles the sound that could exist without them.
