Description

The COBB Titanium Cat-Back Exhaust is engineered for superior build quality, style, and performance for your 2011+ Subaru WRX or STI Sedan. Constructed from Grade 4 titanium tubing, this cat-back exhaust system provides exceptional corrosion resistance and impact protection. The use of back-purged welds ensures weld integrity and longevity, preventing contamination failures. Its slip-fit connections offer a high degree of adjustability during installation, while the blued titanium tips add a distinct aesthetic touch. Weighing in at a mere 24lbs assembled, this system is nearly 50% lighter than its stainless steel counterparts, contributing to improved vehicle dynamics. This cat-back exhaust is confirmed to fit Subaru Impreza models from 2011-2014, and WRX/STI models from 2015-2021. It is not an emissions-related part and can be used on emission-controlled vehicles.
