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 variable pipe diameters to remove the drone at around 70-80mph.

The Helmholtz Chamber design is the only proven effective way to kill drone in the Alfa Romeo 4C. If you want a true sport tuned Euro sound for your 4C and no drone, this is it. It gives the 4C some of that classic Alfa Romeo exhaust note that Alfisti love.

The fit and finish produced by Quicksilver UK is superb and what you’d expect for a car of the 4C’s level. 

Optional — Alfa Romeo 4C factory Mid-Pipe
If your 4C has a modified mid-pipe, you will need to restore it to OEM spec to fit the Helmholtz system. Select that option, shipping is included — Lower 48 states only.
