If you’re looking to unleash the most power out of your Alfa Romeo Stelvio Quadrifoglio, the Ragazzon Downpipes is one of the best options! You have the option to choose from a catless downpipe, or a 200cell (cpsi) catalytic converter.
Crafted in Italy with wide 76mm (3") diameter piping. Click her to grab the Ragazzon Axle-Back and Midipe to make the complete system!
Requires ECU remap/tune. Compatible with Euro6-6B Engine (before 08/2018)
Connecting sleeves are required (sold separately here). Use 65mm to 76mm if connecting these downpipes to your factory midpipe, or use the 76mm to 76mm sleeve if connecting these downpipes to a Ragazzon midpipe.
