Alfa Romeo Giulia 2.9T QV Catless Down Pipes

Unleash the full performance of your Alfa Romeo Giulia Quadrifoglio 2.9L Twin-Turbo V6 with these Catless Downpipes, engineered for track use only. By removing the restrictive factory catalytic converters, these downpipes allow for maximum exhaust flow, reduced backpressure, and significant gains in horsepower, torque, and turbo response.

Crafted from premium stainless steel, they are built to withstand extreme heat and stress while maintaining long-term durability. Precision TIG-welded with OEM-style connections, these downpipes provide a direct bolt-on installation with no cutting or permanent modifications required.

In addition to noticeable performance improvements, these catless downpipes deliver an aggressive, race-inspired exhaust tone, amplifying the character of the Giulia QV’s twin-turbo V6. To maximize performance and reliability, pairing with a performance ECU tune is highly recommended.

⚠️ Note: These downpipes are designed specifically for the Giulia Quadrifoglio (2.9T V6) and do not fit the Stelvio Quadrifoglio. They are intended for off-road / track use only and are not legal for street use in many regions.
