Resonator Bypass X-Pipe
A stainless steel A crossover pipe joining the two exhaust banks into an X shape, smoothing flow for a fuller, balanced tone. for the Maserati Quattroporte (2004-2012) that replaces the factory mid-pipes and resonators to free up exhaust flow. Investment-cast for the best possible flow and built from 14-16 gauge mandrel-bent T304 stainless steel, it sheds 4 lb from the car and delivers a major improvement in power through the RPM range. Expect a louder, more aggressive exhaust note with more of the V8's natural tone coming through. Bolt-on installation, no cutting or welding. Select your year range, 2004-2006 or 2007-2012, when ordering.
