Product Description

The Invidia HS08SW5GT3 Q300 Cat-Back Exhaust is a performance exhaust system engineered for the 2008-2014 Subaru WRX Hatchback and compatible Impreza hatch variants such as the 2.5 GT and WRX Premium/Limited models. Constructed from high-quality SUS304 stainless steel with mandrel-bent piping and a Q300 muffler design, this exhaust system enhances exhaust gas flow compared with the stock system. Increased flow can improve throttle response, torque, and horsepower, while the flat-bottom muffler design and polished rolled tip provide a refined, sporty rear aesthetic.

Installation is straightforward with a direct bolt-on design that utilizes OEM hanger locations - no cutting or welding required. The single rolled stainless steel tip completes the performance look and offers a rich, balanced exhaust note that suits both everyday driving and spirited performance. Durable construction with precision flanges and TIG welding ensures reliable, long-lasting performance for your Subaru WRX hatch.
