With the exhaust manifold from Giannelli and its correct tuning, you can achieve a performance increase of 2 HP. The resonance speed is reached at about 6.500 rpm and lasts until about 8.500 rpm. There is no information about the torque, but since power is mainly defined by torque and rpm, the torque should also increase.
Giannelli stands out positively due to its price, but unfortunately it has to be slightly reduced in quality. We therefore recommend that you apply two more coats of clear lacquer to your exhaust in addition to the factory applied layers of clear lacquer. This way you can enjoy it longer.
