Larini Systems Sport Cats for Maserati GranTurismo (2008-2019)

Larini Systems Sport Cats are a powerful upgrade for the Maserati Granturismo, unleashing +18hp and +22 ft/lb of torque from this bolt-on performance upgrade.

The factory Maserati GranTurismo Catalytic sections incorporate a pair of 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 Sport Cat Solution with pipework offering improved flow, utilizing a more free flowing design with Larger Diameter Tubing, forcing the gasses to 'merge' more effectively helping to create a true 'scavenging' effect which ensures that expelled exhaust gas pulses are rapidly 'sucked' away from the engine through a set of High Flow 200 Cell, Tri-Core, Metallic Larini Sports Cats, which offer near De-Cat pipe levels of Performance. Their efficiency and emissions performance levels mean that you are able to achieve more Horsepower and Torque while remaining Check Engine Light Free and still achieving excellent emissions!

Once the Larini Sports Cat Sections are fitted, the increase in low down / 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.
