This exhaust system is constructed from 100% stainless steel and manufactured in the USA by Magnaflow. It features Magnaflow's NDT (No Drone Technology) with a Helmholz resonator to reduce drone at low RPMs while maintaining an aggressive tone under acceleration. The system utilizes a 3.0" diameter and mandrel bends to increase exhaust flow and facilitate faster turbo spool.
Show original supplier description
The Centerline Competizione (Race) EVO exhaust system is a premium cat-back exhaust designed to replace the restrictive factory system on 2017-2022 Alfa Romeo Giulia models (excluding the Quadrifoglio). This 100% stainless steel system is manufactured in the USA by Magnaflow exclusively for Centerline, aiming to provide a deep, sporty exhaust note during acceleration while maintaining a quiet and comfortable experience at cruising speeds. The system boasts a large 3.0" diameter with smooth mandrel bends, designed to increase exhaust flow and promote faster turbo spooling. Its construction includes a high-flow Magnaflow resonator and a Y-pipe that leads to dual 3.5” brushed finish stainless steel tips, replacing the factory's faux exhaust outlets. Installation of the complete exhaust system is straightforward, typically taking around 1 hour with standard hand tools. This system is compatible with all 2017 and newer Giulia, Giulia Ti, Giulia Sprint, and Giulia Veloce models equipped with the 2.0T engine, including Q4 AWD variants.
