Invidia 11+ STI/WRX Sedan Only 76mm Q300 Titanium Tip Cat-back Exhaust

This Invidia Q300 cat-back exhaust system is made specifically for the 2011-2014 Subaru Impreza sedan models. It's designed to replace the factory exhaust from the catalytic converter back, offering a noticeable improvement in both sound and exhaust flow. If you're looking to give your Impreza a more aggressive exhaust note without being overly loud, this system is a solid option.

The Q300 series is known for its refined sound profile, aiming for a deep, sporty tone that's enjoyable during spirited driving but not intrusive for daily commutes. This particular system features 76mm (approximately 3-inch) diameter piping, which is larger than stock and helps reduce backpressure, allowing the engine to breathe more freely. The titanium tip adds a touch of visual flair, giving your rear end a more performance-oriented look. Invidia uses well-built stainless steel for the main piping and muffler construction, which holds up well against corrosion and the elements.

When installing this cat-back system, you'll typically find it's a direct bolt-on affair, meaning no welding or cutting is required. It's designed to bolt up to the factory catalytic converter flange. You'll want to ensure you have new exhaust gaskets on hand for a proper seal at the connection point. The result is an improved exhaust note and potentially a slight increase in throttle response due to the better flow.
