Unitronic's 3" Downpipe fits all Audi B6 1.8T Quattro vehicles equipped the manual 5 Speed Gearbox. Constructed of 3" T304 stainless steel mandrel bent tubing, T316 stainless steel flanges, a corrugated stainless steel flex section, and TIG welded fabrication, this downpipe is built to outlast and outperform the competition. All Unitronic downpipes come equipped with a 200-cell high flow metallic catalytic converter and all transitions are flow-matched to allow for maximum performance and airflow. In addition, Unitronic exhausts feature easy-to-use v-band flanges to ensure a fast and effortless installation and precise fitment.  To finish it off, an OEM-inspired catalytic converter heat-sheild protects against unwanted heat radiating in the exhaust tunnel. Every Unitronic Exhaust System comes embossed with a Unitronic logo, equipped with an individualized serial production plate to ensure authenticity, and a brushed matte finish for an elegan appearance that will last a lifetime.
