Overview

The Cobb Tuning SS 3" Cat-back Exhaust is a direct replacement system for Subaru WRX and STI Hatchback models. It features a straight-through muffler design that minimizes bends and reduces back-pressure for improved flow. The exhaust is constructed from 304 stainless steel and is TIG welded for durability. It includes quad polished exhaust tips that fill the factory bumper cut-outs and is designed to fit with either the Subaru factory downpipe or the Cobb 3" SS Downpipe.
Show original supplier description
This system features a quad rear-exit configuration with polished tips, offering a distinct aesthetic and an aggressive exhaust note. Engineered for a direct bolt-on installation, the 515101 utilizes factory exhaust fitment locations, ensuring a straightforward process. It is designed to work seamlessly with either the stock Subaru downpipe or the Cobb 3-inch SS Downpipe. The system comes complete with all required gaskets and hardware, simplifying the installation. This cat-back exhaust is specifically designed for the 2011-2014 Subaru WRX Hatchback and the 2008-2014 Subaru STI Hatchback. It's important to note that while the product description from Custom Offsets and Fitment Industries mentions fitment for the 2025 Ram 1500, this appears to be an erroneous inclusion as other sources consistently list Subaru models exclusively for this part number.
