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
- SUS304 Stainless Steel Construction: Mandrel-bent 76mm piping for unrestricted flow, reduced back pressure, and measurable HP/torque gains.
- 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.
- Flat-Bottom Aerodynamic Muffler: Improves high-speed stability and reduces weight without sacrificing strength.
- OEM-Compatible Fit: Direct bolt-on using factory hangers and flanges (includes new gaskets and hardware).
Product Notes
- Boosts horsepower, torque, and throttle response while remaining emissions-compliant and street-legal.
- Deep, refined tone ideal for daily driving with aggressive growl under load – no excessive drone.
- Titanium tips resist discoloration for long-lasting shine.
Warranty: Lifetime limited against manufacturing defects.
Installation Notes
- Professional installation recommended for precise alignment.
- Bolt-on design – no cutting or welding; uses OEM mounting points.
- Check clearance with aftermarket downpipes or lowered suspension.
