Smooth, larger diameter mandrel bent piping significantly reduces power robbing exhaust backpressure and corrosion resistant aerospace grade T-304 Stainless Steel is used throughout ensuring a system that will last the life of the vehicle.

Cobb's system replaces the heavy and restrictive factory exhaust with a lightweight 3" mid-pipe that starts after the factory catalytic conveter (downpipe) and leads to a free-flowing "Y" pipe section. The exhaust gases are split into two 2.5" sections and directed into Cobb's Sport Mufflers that feature a low-restriction, straight through design. The mufflers are finished in tasteful angle cut oval tips that have been specially designed to match the styling of the Legacy rear bumper. The complete system is a direct replacement for the original factory exhaust and requires no cutting or welding for an easy installation.

The result is improved engine response and a deeper exhaust note that provides a sporty tone during heavy acceleration while remaining subtle and easy to live with during daily commutes. Fully conforms to legal sound requirements (95 dB limit) while also remaining fully emissions legal and warranty friendly.
