Invidia 10+ Legacy Dual Q300 Cat-back Exhaust

Performance and Sound Designed for the Legacy 2.5L GT

The Invidia Q300 Cat-Back Exhaust for the 2010-2014 Subaru Legacy 2.5L GT Sedan is built for enthusiasts who want a deep, refined exhaust note with noticeable performance gains. This system is engineered with mandrel-bent 60mm (2.36”) piping and a high-flow design that reduces backpressure while improving exhaust flow. The result is improved throttle response, smoother power delivery, and gains in both horsepower and torque. Designed specifically for the turbocharged 2.5L GT, this exhaust balances daily driving comfort with performance sound — no drone, just clean, deep tones under acceleration.

Premium Stainless Steel Construction and Polished Finish

Invidia constructs the Q300 series using full SUS304 stainless steel, ensuring long-term durability and resistance to corrosion. The piping and mufflers are TIG-welded for strength and precision, and the exhaust ends with quad 101mm (4”) polished stainless steel tips, giving the rear of the Legacy a sleek, aggressive look. Each system is finished with a mirror polish for show-quality appearance. The exhaust’s layout features dual mufflers with a straight-through design, which allows optimal flow while keeping sound levels refined and street-friendly.

Bolt-On Fitment with OEM Compatibility

This exhaust is a direct bolt-on system designed to work with the factory components. No cutting, welding, or modification is required for installation. It reuses the factory hanger locations, making it a straightforward install for any garage or performance shop. The Q300 also retains compatibility with factory emissions equipment and can be paired with aftermarket downpipes or other upgrades for even more performance benefits. Gaskets and hardware are included to ensure a proper seal and hassle-free installation.

Whether you're daily driving, spirited cruising, or hitting the track, the Invidia Q300 delivers consistent performance and a sound you’ll love.
