Top Gears new sport downpipe for all 2.0L Giulia & Stelvio models delivers smooth power and aggressive sound, all while remaining emissions friendly.
This downpipe is a direct replacement for the factory downpipe/catalyst assembly. It is built around a 200 CPSI metallic catalyst, which contains some of the highest levels of precious metals in the industry. The shape of the unit was optimized for high flow with smooth bends and large, 3" diameter tubing. This allows it to deliver the increased power, torque, and throttle response you want without sacrificing any performance at all
Power increases are immediately noticeable, especially in the mid-range and at high RPMs. Dyno testing has shown a 7.5 HP increase, along with an 11 lb/ft increase in torque.
This aftermarket downpipe is 2.3KG lighter than the OEM part reducing the weight of your Giulia / Stelvio. The original heat shield can be reused with the aftermarket part too! to maintain OEM heat management under the bonnet making this part the number one choice in aftermarket High-Flow cats for the Alfa Romeo Giulia.
Please see a customer video for the sound comparison of OEM & Top Gears catalytic you will notice a deeper tone.
