3" Cat-Back Exhaust System

The COBB Tuning SS 3" Cat-Back Exhaust is meticulously crafted from 304 stainless steel, featuring mandrel-bent tubing throughout. This construction method ensures consistent pipe diameter and optimal flow, which directly contributes to reducing exhaust backpressure. Lower backpressure allows the turbocharger to spool more efficiently, leading to faster boost response and sustained power. Engineered specifically for the GD chassis (2002-2007 Subaru WRX EJ20/EJ255 and 2004-2007 WRX STI EJ207), this cat-back system is designed to connect directly at the catalytic converter outlet. It features correct routing and hanger positions that match the factory setup, making it a straightforward bolt-on installation. All necessary hangers, gaskets, and hardware are included for a complete package. Beyond its performance benefits, the COBB Tuning cat-back exhaust is tuned to deliver an intentional performance sound. This balance ensures a more enjoyable driving experience for both spirited driving and daily commuting. This cat-back exhaust is a testament to their commitment to engineering integrated systems that deliver consistent and reliable results, complementing their other performance offerings for the Subaru platform.
