Alfaworks 4C Helmholtz system

from 645.00

Alfa Romeo 4C Helmholtz Exhaust
This is a custom tuned Alfa 4C exhaust system with Helmholtz resonator. It is a straight through system and uses a resonator and tuned pipe diameters to remove the drone at around 80mph.

The Helmoltz Chamber design is the only proven effective way to kill drone in the 4C. If you want a sport tuned Euro sound for your 4C and no drone, this is it.

This system also includes carbon tips which can be angled as you want and provide a nice finished look to the back of the Alfa Romeo 4C. The adjustable angles of the tips will help make installation and final fitting easier than systems with pre welded tips.

The system utilizes two different diameter pipes to produce a sound with much more depth than Alfa's race exhaust and at idle it retains a purposeful note where as the standard system can sound flat and unfinished.

Select the optional system without the resonator for max volume and a 5.5 lb. weight savings over the Alfa factory race exhaust.

Weight of the system with resonator is only 3.3 lbs. heavier than Alfa's race system. Easy installation retains the factory exhaust exits, and it's compatible with both the 4C Coupe and Spider. Clamps are included. See the Video.
