Unitronic Performance Downpipe for EA888 Gen 4 EVO FWD

The Unitronic Performance Downpipe for the MK8 GTI® equipped with the 2.0TSI EA888 EVO4 engine is a direct bolt-on upgrade, designed to optimally eliminate unwanted restrictions in the factory downpipe, reduce turbo lag and enhance the exhaust note. It utilizes a 5” 400cpsi ultra high output (UHOX) catalytic converter, designed in partnership with Unitronic, from our emissions partners at Global Emissions Systems Inc (GESi).

Paired with Unitronic Stage 2 E85 Performance Software and other supporting bolt-ons, this Performance Downpipe helps yield up to 417HP / 426LB-FT with more to come.
