The Invidia Q300 3.0" Cat-Back Exhaust is a refined performance exhaust upgrade for the 2022–2026 Subaru WRX. Designed for owners who want improved exhaust flow, a deeper tone, and a cleaner rear-end appearance without excessive volume, the Q300 delivers a sporty sound profile that stays more daily-driver friendly than Invidia’s louder N1 and R400 systems.

Built from T304 stainless steel, this system uses 1.5mm thick mandrel-bent piping, CNC-machined flanges, and robotic welds for strength, fitment, and durability. The 76mm main piping splits to 60mm dual sections, helping improve exhaust flow while maintaining a balanced quad-tip look at the rear of the VB WRX.

Key Features

• Refined Q300 Sound: Quieter than Invidia’s N1 and R400 systems while still delivering a rich, deep, sporty exhaust note.
• 3.0" Main Piping: 76mm main pipe splits to 60mm dual piping for improved flow and balanced rear fitment.
• T304 Stainless Steel Construction: Durable stainless construction helps reduce the risk of cracks, breaks, rasp, and vibration.
• 1.5mm Thick Mandrel-Bent Piping: Smooth bends help maintain consistent exhaust flow with minimal restriction.
• 101mm Exhaust Tips: Large 4.3" tips fill the rear bumper openings with a clean performance look.
• Multiple Tip Options: Available with rolled or single-layer tips in titanium or stainless steel finishes.
• Cannon-Style Mufflers: Designed for efficient flow with controlled volume and minimal back pressure.
• CNC-Machined Flanges: Precision flanges support proper fitment and long-term durability.
• Robotic Welds: Consistent weld quality for strength and clean appearance.

Why We Like It

The Q300 is the Invidia exhaust we like for VB WRX owners who want a more polished, mature tone. It adds the deeper sound and cleaner look you want from a cat-back, but it keeps volume more controlled for daily driving. If the N1 or R400 feels like too much, the Q300 is the smarter street-friendly choice.

Sound & Performance

Invidia’s Q300 muffler design focuses on efficient exhaust flow while keeping sound levels in check. The result is a deeper, sportier tone that enhances the FA24’s natural sound without adding excessive harshness or unwanted volume. The optimized piping layout helps reduce back pressure and supports improved throttle response and exhaust flow.
