I've heard a number of times that the 2007 323 is a detuned 2006 325? Is this true? Are there any vendors that carry performance parts and/or ECU upgrades to up the performance? I heard one way of restricting the HP is by limiting the exhaust flow. The headers and downpipes are smaller... can anyone confirm?
