Maxflo Performance Exhaust System
Maxflo performance mufflers for the Maserati Quattroporte (2004-2012), built from 14-16ga CNC Bent over an internal mandrel so the tube keeps a constant diameter through the bend, unlike crush-bending. T304 stainless steel with deluxe quad-style tips in your choice of finish. Fabspeed says to expect a noticeably louder tone from the Ferrari-built V8, along with sharper throttle response, while staying tame enough for daily driving. The system saves about 20 lbs (9 kg) from the factory muffler setup. Installation is a straightforward bolt-on job with no cutting or welding.
