SS 3" Downpipe

The COBB Tuning SS 3" Downpipe is engineered to enhance exhaust flow and reduce restrictions for performance-oriented vehicles. Its design incorporates minimal bends to ensure a smoother path for exhaust gases. Key features include two O2 bungs to accommodate both factory and aftermarket sensors, facilitating easy integration with existing or upgraded systems. The downpipe utilizes the stock donut gasket and factory spring bolts at the trailing-end flange, ensuring a proper seal, proper fitment, and long service life while also aiding in flex. A custom-cast 3" flat flange provides a true mating surface at the O2 housing, further contributing to an improved seal and reduced noise compared to alternative methods. Installation is rated at Level 2, indicating it is an easy procedure achievable with basic tools. This downpipe is designed to work with factory-style O2 housings and can be fitted to the OEM exhaust system or paired with the COBB Tuning Catted Mid-Pipe for a complete performance exhaust solution. It is specifically designed for the Mitsubishi EVO X (2008-2015) and Ralliart (2009-2015) models.
