The COBB Tuning Titanium 3" Cat-Back Exhaust System is meticulously engineered for the 2011-2014 Subaru WRX Hatch and 2008-2014 Subaru WRX STI Hatch, offering a blend of superior build quality, distinctive style, and enhanced performance. Constructed from Grade 4 titanium tubing, this system provides exceptional corrosion resistance and robust protection against impacts. The use of back-purged welds ensures weld integrity and longevity, preventing contamination failures. For ease of installation and a customizable fit, the entire system employs slip-fit connections. Additionally, the blued titanium tips contribute a unique aesthetic touch and allow for further adjustability. Weighing a mere 24lbs assembled, this cat-back exhaust is nearly 50% lighter than traditional stainless steel systems, contributing to improved vehicle dynamics. While many titanium exhausts can produce a 'tinny' sound, the bespoke suitcase muffler and overall build quality of this COBB system deliver a refined, aggressive exhaust note that aligns with the signature COBB sound profile. Key features include Grade 4 Titanium Construction with Back-Purged Welds, a lightweight design (24lbs assembled), Blued Titanium Tips with COBB Logo, High Adjustability via Slip-Fit Connections, and a Bespoke Suitcase Muffler. The benefits are increased power over the OEM exhaust and a louder, more aggressive exhaust note.
