PRODUCT DESCRIPTION
Downpipe for 1.8T 20V engines - front-wheel drive (FWD, not Quattro). This pipe removes the stock catalytic converter, allowing the engine to generate more power at lower RPMs.
Compatible with all 150 HP and 180 HP engines with K03/K03s turbochargers.
Our downpipes are made of high-quality SAE 304 stainless steel with 1.6 mm thick walls for increased durability compared to other common exhaust systems made of 1.2 mm steel. This prevents the exhaust system from cracking or even bending.
Internal diameter: 54 mm
External diameter: 57 mm
Flange internal diameter: 76 mm
