Alfa Romeo Giulietta 940 Valved Exhaust System (2010-2020)

The Alfa Romeo Giulietta 940 exhaust in detail.

At Alfa Romeo, engineering has always been a matter of temperament, and the Giulietta 940 carries that heritage in an everyday hatchback. In the version this page covers, its turbo engine delivers 235 hp and 340 Nm, from 2010 to 2020; yet modern engines have been tamed by regulations, and the factory sound does not tell the legend of the Biscione.

The Rog valved cat-back, also known as a valve exhaust, tells its story: a full, Latin tone, assertive character under load, clear crackles on the overrun when the valves are open. Closed again, they give the compact back its everyday discretion, in town as on long stages.

We build the system to your VIN, checked before production; it fits without welding, with clamps and gaskets, in about two hours, with the original valve control if the Giulietta has it, and the Rog remote otherwise.

The Giulietta entrusts emissions control to a downpipe placed just after the turbo, a part the page offers to replace under the “Manifold” option. Fitted alone, it changes the voice and a few kilos; it is the ECU remap that turns it into horsepower, with the result depending on the tune. A Giulietta that also handles daily journeys will keep the 200-cell downpipe, the one that maintains emissions control; the 100-cell will be accepted or not depending on the car and the rules in your country, and the decat version is reserved for track use, far from this hatchback’s purpose. 304 stainless steel and titanium, around 40% lighter and offered in three colours, share the choice of material.
