Invidia 2011–2014 Subaru WRX/STI Sedan Q300 Quad Titanium Tip Cat-Back Exhaust
The Invidia Q300 Quad Titanium Tip Cat-Back Exhaust (HS11STIG3T) is precision-engineered for 2011–2014 Subaru Impreza WRX and STI Sedan models, delivering enhanced performance, a refined exhaust tone, and premium styling.
Constructed from mandrel-bent SUS304 stainless steel with a 76mm piping diameter splitting to 60mm, it features Advantex acoustic technology for optimized back pressure, flat-bottom muffler for aerodynamics, and dual rolled titanium quad tips (110mm diameter) with robot TIG welding for superior durability and a stealthy, deep boxer rumble.
Key Features

- Advantex Muffler Technology: Continuous internal piping with acoustic dampening for a sporty, drone-free sound.
- Quad Titanium Tip Design: Rolled titanium dual 110mm tips for heat resistance, premium aesthetics, and aggressive rear stance.
