SS Turbo-Back Exhaust System

The COBB Tuning SS 3-Inch Turbo-Back Exhaust is engineered as a comprehensive power upgrade for your 2015+ Subaru STI. This system offers a straightforward plug-in and bolt-on installation process, delivering significant power gains, exceptional build quality, and a distinct exhaust note. The turboback package integrates two key components: the COBB 3" SS Downpipe, featuring a cast bellmouth and a high-flow catalytic converter for optimized exhaust flow, and the COBB 3" SS Quad-Tip Cat-Back Exhaust, known for its meticulous fabrication and resonant sound profile. Constructed from SUS304 stainless steel, the piping is CNC mandrel-bent for optimal flow, transitioning from a single 3-inch diameter to dual 2.5-inch pipes. The system is finished with quad 3.5-inch double-wall tips. This exhaust system is specifically designed for the Subaru WRX STI [VAB] chassis (2015, 2016, 2017) with the EJ25T engine. It comes with a 1-year limited warranty.
