The Unitronic High-Flow Performance Downpipe for 2.5TFSI EVO (DAZA) engines is a direct bolt-on upgrade, designed specifically to eliminate unwanted restrictions in the factory unit and increase power with the help of Unitronic Stage 2 Software. It also helps reduce turbo lag and enhance the exhaust note, while utilizing a GESi 5” G-Sport Ultra High Output UHO+ 400cpsi Catalytic Converter which is engineered to meet or exceed emissions standards. The Unitronic High-Flow Performance Downpipe comes bundled with Unitronic Midpipes to further eliminate restrictions and when combined with Unitronic Stage 2 Performance Software, yields output of up to 621HP/564LB-FT with E85 and other supporting hardware modifications.
