Larini Systems - Sport Cats for Maserati Quattroporte |  |  |  |  | Order your Larini Systems - Sport Cats for Maserati Quattroporte Today! |  | |  | | Larini Systems Sport Cats are a powerful upgrade for the Maserati Quattroporte (4.2L DuoSelect F-1 and 4.2L / 4.7L Automatica models), unleashing +18hp and +22 ft/lb of torque from this single bolt-on performance upgrade. The factory Maserati Quattroporte cat sections incorporate a pair off restrictive Primary cats. This was Maserati’s cost-effective solution to allow the cat sections to meet emissions, which ultimately stifles true power output from the Ferrari-derived (F430 de-tuned) engine. However, there is a better solution. Formula Dynamics and Larini have developed a cat section with pipework offering an internal area that offers greater volume capacity as a large diameter tube with the necessary ground clearance. Furthermore, by forcing the gasses to ‘merge’ effectively creates an optimal pressure differential aka a true ‘scavenging’ effect which ensures that expelled exhaust gas pulses are rapidly ‘sucked’ away from the engine through a set of high flow Metallic Larini ‘Sports’ Cats, which offer near de-cat pipe levels of performance assistance. Their efficiency and emissions performance levels mean that you are able to achieve more horsepower and torque while still meeting stringent emissions standards! Once the Larini ‘Sports’ Cat Sections are fitted, the increase in low / mid range torque gain over standard performance levels will quite simply stagger the driver at first. Throttle response will be akin to a switch, and offer the true Ferrari performance levels that most Maserati owners desire. Furthermore, dual-walled catalyst casings and all Metallic internal catalyst construction ensure true component durability and longevity. Replacing the bulky and restrictive factory catalysts with Larini High Performance Sport Catalysts allows the V8 engine to really sing and offer a crisp, high pitched, note all the way to the rapidly approaching red-line. ** Please note that it may be illegal to remove a properly functioning catalytic converter in your area and that aftermarket catalytic converters are not legal for installation in California on OBD II vehicles. | |  We accept Visa, Mastercard, PayPal via (paypal@formuladynamics.com), Wire Transfers or Cash for all Products.
