Description

Premium valved exhaust system for Alfa Romeo Giulia GTAM & Stelvio Quadrifoglio 2.9T V6 Bi-Turbo. High-flow stainless steel design delivers deeper sport sound, reduces backpressure and improves throttle response.

Product Overview

Factory exhaust systems on Alfa Romeo Giulia GTAM and Stelvio Quadrifoglio 2.9T V6 Bi-Turbo are overly restrictive with muted sound and excessive backpressure, dulling the iconic V6 turbo performance. Our upgraded valved cat-back exhaust system is precisely engineered for these flagship performance models to unlock genuine racing sound and improved engine efficiency.

Built with premium T304 stainless steel and seamless mandrel-bent tubing, this exhaust eliminates airflow turbulence and reduces exhaust backpressure for faster turbo spool and sharper throttle response. The electric valvetronic system provides dual-mode sound performance: quiet and drone-free for daily highway cruising, while releasing a deep, aggressive V6 growl in sport/race mode. All OEM mounting points, sensor ports and fittings are fully reserved for 100% bolt-on installation without cutting or welding, fully reversible to stock.
