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 withstand the test of time, while performing to the max. 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 an easy-to-use v-band exhaust fastening system 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 elegant appearance that will last a lifetime.
