Product Description

The Invidia HS05SL1GT3 Q300 Cat-Back Exhaust is a high-quality exhaust upgrade engineered for the 2005-2009 Subaru Legacy GT powered by the 2.5-liter turbocharged EJ255 engine. Built from premium SUS304 stainless steel with mandrel-bent piping and a thoughtfully tuned Q300 muffler, this cat-back exhaust enhances exhaust flow compared to the stock system, helping to improve throttle response, horsepower, and torque. The quad rolled stainless steel tips deliver an aggressive and sporty rear look while contributing to a robust exhaust note that complements the turbocharged engine's character.

Installation is straightforward with a direct bolt-on design that uses factory hangers and included hardware - no cutting or welding is required. The optimized muffler design offers a deeper, more performance-oriented sound without excessive cabin drone, making it suitable for both spirited driving and daily use. Premium materials and craftsmanship ensure long-lasting durability and resistance to corrosion.
