Maserati GranTurismo S - Valvetronic FI Exhaust

Maserati GranTurismo S 4.7 V8 (2008-2014) Fi Exhaust (Frequency Intelligent Exhaust) high-performance valvetronic exhaust system is direct replacement bolt on system manufactured out of a high-grade T304 stainless steel that offers an exhilarating soundtrack.

The Fi EXHAUST system is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. On average horsepower is expected to increase from 5-10% after installing a full catless system, which includes a valvetronic catback and ultra-high flow downpipe.

When valves are closed exhaust gasses are routed through the muffler resulting in a low-profile comfortable drive. However, when the valves are fully open an intense and sporty soundtrack is produced.

Switching between street and race sound profiles can be done using factory exhaust/sport button or drive mode, or optional Fi EXHAUST remote control and mobile App.

The unique sound and performance for Maserati GranTurismo S is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.

Please note each part of the Fi EXHAUST system needs to be ordered separately.
Different exhaust parts are offered depending on the vehicle version.

Please note that the actual product may vary in appearance depending on the year of the car and area. The exhaust system is also subject to changes to the design over an extended time period. Product pictures are for illustration purposes only.

VALVE

All Fi EXHAUST exhaust systems are equipped with valvetronic technology. This technology is not only used to control sound volume, but also enhance overall performance of the vehicle. Before the inception of this technology, horsepower and torque were irreconcilable contradictions in the design of exhaust systems. This allowed sports cars to have high torque power at low rev speeds and even higher horsepower capability at high rev speeds.

DOWNPIPE (optional)

Catless Standard Version

The ultra-high flow catless downpipes remove restrictive factory catalytic convertor. They increase exhaust gas flow and performance gains, produce higher sound volume. And is usually recommended option going further with ECU tuning.

Catless Sensor Version

The ultra-high flow catless downpipes remove restrictive factory catalytic convertor. They increase exhaust gas flow and performance gains, produce higher sound volume. The downpipe is also equipped with a dummy oxygen sensor to reduce a chance of the check engine light (CEL) being triggered.

Race 100Cell

This kind of catalyst is generally used in race cars , so it is often called “racing catalyst”. With the larger cells and fast exhaust flow rate, it is smooth, durable and do not have refractory wool burn-out problems. The higher the number of the cells, the smaller and denser the hole is. The higher the back pressure, the more it can enhance torque performance, while the opposite is true for increasing horsepower.Converting your stock catalyst converter (400~800 CPSI) into our metallic catalyst converters will result in significant enhancements in airflow discharge that circumvents the limitations and parameters set by car manufacturers.

REMOTE CONTROL

Standard Remote Control

Standard Remote Control system includes a control box and 2 standard remote controls, which allows users to open/close the exhaust valves or set on Auto Mode. Auto Mode settings need to be applied manually to the control box.

Fi EXHAUST Pro Control System (optional)

Fi EXHAUST Pro Control System control system consist of intelligent control box, sporty 2 button style remote control and mobile App.

-The mobile App scans and deletes CEL using manual or Auto scan on the engine startup.

-Monitor real-time valve status with Fi EXHAUST Pro App’s intuitive and friendly interface.

-Assign Auto Mode data values. Afterwards the system will intelligently detect engine RPM/Speed/Turbo Boost and turn on the valves.

-Each remote control button can be assigned with 1 function to open/close the valves or activate Auto Mode delivering more precision in the hands of the driver.

-The design is smooth and offers a nice grip, and the aluminum alloy ring can be customized in 14 different colors or switched to forged carbon with a unique marble like texture.

TIPS:

Stainless with polish (standard):

Titanium Blue (optional):

Titanium blue tips are heat colored to achieve a beautiful color transition from silver to blue and purple color combination.

Diamond Black (optional):

After electroplating and double polishing process a shiny and glossy color surface is achieved on diamond black tips. Each tip is engraved with Fi EXHAUST logo.

Gold (optional):

After electroplating and double polishing process a shiny and gold color surface is achieved on gold tips. Each tip is engraved with Fi EXHAUST logo.

Carbon Fiber (optional):

Made out of a high-grade carbon fiber that can withstand high temperatures. The inserts come standard in silver. However, the inserts can be customized in other colors like gold and black. Fi EXHAUST logo engraving is available in many color variations like red and black, gold or black to match with the insert color.

OPTIONAL CERAMIC COATING

Fi EXHAUST eliminates traditional thermal insulation materials that contain toxic substances, and directly coats the exhaust pipe with a nano-ceramic coating to protect from corrosion, reduce heat exposure to heat sensitive components in the engine bay and keeps temperature low. It’s a great way to improve longevity of the exhaust and other components prone to thermal degradation like wiring.
