Fabspeed Maxflo Performance Package for Maserati Quattroporte (2004–2006)

The Quattroporte package combines Fabspeed Maxflo mufflers, a resonator bypass X-pipe and a BMC air filter. Select the tip finish and decide whether ECU performance software is included, rather than assuming every configuration contains tuning. Fort Washington, Pennsylvania is home to Fabspeed Motorsport, whose exhaust, intake and ECU tuning development for Porsche and other sports cars includes dynamometer testing and road and track evaluation.
