Description

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.

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-shield protects against unwanted heat radiating in the exhaust tunnel. Every Unitronic Exhaust System comes equipped with a brushed matte finish for an elegant appearance that will last a lifetime. There's simply nothing like it!
