MASERATI GranTurismo Coupè 4.2i V8 (405 Hp) 2007-> (with valve)

100% Stainless steel system Oversize 2 x Ø65mm

The exhaust system for MASERATI GranTurismo Coupè 4.2i V8 (405 Hp) is composed by: front pipe right + left with a metallic catalytic converter, a centre exhaust (or centre pipes kit) + "X-Pipe", intermediate pipes kit and the rear exhausts.

The catalytic converter, as in the Supersprint tradition, is replaced by a HJS metallic unit with 200 cells per square inch. It's much more efficient and free-flowing but at the same time offers an optimal reduction of pollutant gas.

If you're looking only for a more involving and sportier exhaust tone and don't want to replace the stock catalysts the recommended setup is composed by rear exhaust right - left with bypass valves.

Following our very long tradition (est.1955), the main target is not to change the nature of the car, loosing comfort in the process, but to make the engine note more pleasant and distinctive, without being excessive, but even more important, to increase the performance. We still offer a louder, more aggressive setup for enthusiasts.

The look is the perfect match of sportiness and class, with rear exhaust available with quad pipes setups, two for each side (100 mm), perfectly integrated in the bumper line, for a sporty but still elegant result.
