Exhaust system with Helmholtz resonator. This is a straight through system and it uses a resonator to remove the drone at around 80mph. It comes with carbon tips which can be angled as you want. The system also utilises two different diameter pipes to produce a sound with much more depth than Alfa Romeo's own 4C Race exhaust and at idle it retains a purposeful note where as Alfa's Standard system can sound flat and unfinished. We have designed the system so you can remove the Helmholtz resonator and fit our SuperSport right hand pipe on instead for those days you want to make NOISE! Weight 6kg only 1.5 kilos heavier than Alfa's Race system. [ Ссылка ]
