COBB Titanium Cat-Back Exhaust – 2022+ Subaru WRX

The COBB Titanium Cat-Back Exhaust is a no-compromise system for VB WRX owners who care about weight, sound quality, and premium materials. Built from Grade 1 titanium tubing with Grade 2 titanium hangers, this system offers outstanding corrosion resistance, impact protection, and a distinct motorsport look. Back-purged welds and fully slip-fit connections ensure long-term durability and a highly adjustable, precise fit under the car.

From the pressed front flange that interfaces with the factory donut gasket to the bespoke straight-through oval mufflers and hand-blued titanium tips, every detail is engineered for performance and style. Weighing in at roughly 24 lbs assembled—nearly 30% lighter than stock—this system frees up weight while delivering a sharper, more engaging exhaust note.
