Description
The Unitronic 3" Downpipe for 1.8 TSI Gen 3 FWD MQB vehicles is engineered for maximum performance, durability, and precise fitment. Built from 3" T304 stainless steel mandrel bent tubing, T316 stainless steel flanges, an 8-inch corrugated stainless steel flex section, and TIG welded fabrication, this downpipe is designed to last while optimizing exhaust flow.
Each Unitronic downpipe includes a 200-cell high-flow metallic catalytic converter with flow-matched transitions for maximum efficiency and power. The OEM-inspired catalytic converter heat shield protects against unwanted radiant heat, and the v-band fastening system allows for quick, precise, and reusable installation. Brushed matte finish completes the premium look.
