Product Description

The Invidia HS11STIGTT Q300 Catback Exhaust with Titanium Tips is a performance exhaust upgrade designed for 2011-2014 Subaru WRX and WRX STI sedan applications. Constructed from high-quality SUS304 stainless steel with mandrel-bent piping, this cat-back system improves exhaust flow and reduces back pressure compared to the stock exhaust. Its resonated design delivers a deeper, richer exhaust tone while minimizing unwanted drone during cruising and daily driving.

Equipped with dual rolled titanium tips, the HS11STIGTT not only enhances the rear appearance but also offers excellent corrosion resistance and lightweight durability. The system installs as a direct bolt-on using factory hangers and included hardware, making fitment straightforward for experienced installers and performance enthusiasts. This exhaust is tailored for sedan body styles and does not fit hatchback models. It provides a balanced combination of sound, performance, and style for WRX and STI builds.
