MASERATI GranTurismo S Coupè 4.7i V8 (440 Hp / 450 Hp) 2008->2012 (with valve)

The Maserati GranCabrio Sport and the GranTurismo S Coupè are considered the last ones of the real Maserati cars.

Their high revving, natural aspirated 4.7L V8 engine is perfect candidate for a Supersprint Performance exhaust.

We know the F136 V8 powerplant very well, as it has been originated, developed and updated in various steps on several Ferrari/Maserati models.

The guys at our R&D facility did a lot of work on these cars; always striving for the best results, they did not settle on getting a nicer sound only, but rather they focused on squeezing out the most performance.

Leaving the free-flowing, std. factory headers in place, we have redesigned the entire exhaust downstream, using Oversize diameter, stainless piping.

A set of high-volume HJS Motorsport cats, replacing the restrictive stock components, a new x-pipe mid section and a set of dual sound-mode, R&L mufflers, with vacuum flaps, are exactly what the Maserati Gran Cabrio and GranSport S Coupè need.

The final gains in mid rpm torque and peak horsepower are huge, the sound becomes awesome.

As always, the Supersprint exhaust installs directly, with no modifications needed.

Nonetheless important, the quad-tip design looks killer, beating the dull style of the std. flat-oval tips.

Systems for replacement of kat for OBD II car models (with lambda sensors before and after the kat.)

These systems can only be used for racing purpose exclusively, in conjunction with the modifications of the engine management system. If used with a stock “ECU”, malfunctions may occur. All modifications must be carried out by qualified personnel only, under the liability of the car owner and at his expense.

Supersprint guarantee is limited to the quality, workmanship and correctly fitting to the intended car model for all race products.
