Perfect for your G-model 911. This dual centre-exit exhaust, made from aluminised steel, is specially crafted to keep the sound level at “speech level” while driving. At idle, the car sounds potent and sporty. City driving and cruising are no louder than 76 dB in the car. Resonance/drone is close to zero! Under heavy acceleration and sporty driving, it produces a powerful – but subdued sound that never gets too loud. Does not exceed 85 dB when driving hard
