Description
The Unitronic 3" Downpipe UH024-EXA for 2.0 TSI Gen 3 FWD MQB vehicles is engineered for maximum airflow, durability, and precise OEM-style fitment. Constructed from 3" T304 stainless steel mandrel bent tubing, T316 stainless steel V-band flanges, an 8-inch corrugated stainless steel flex section, and TIG welded fabrication, this downpipe is built to last while optimizing performance.
Equipped with a 200-cell high-flow metallic catalytic converter, all transitions are flow-matched to maximize exhaust efficiency and maintain emissions compliance. An OEM-inspired catalytic converter heat shield protects against radiant heat, and the V-band fastening system allows fast, precise, and reusable installation. Brushed matte finish ensures a premium, long-lasting appearance.
