Invidia Q300 Cat-Back Exhaust w/ Rolled Tips - 2013-2022+ Toyota GR86 86 / Subaru BRZ / Scion FRS

The Invidia Q300 Cat-Back Exhaust is a great choice for GR86, 86, BRZ, and FR-S owners who want improved exhaust flow, a deeper tone, and a cleaner rear-end look without going overly loud. Built from T304 stainless steel, the Q300 is designed to reduce restriction, improve durability, and deliver a rich, sporty exhaust note that stays more refined than Invidia’s louder N1 and R400 systems.

With 70mm mandrel-bent piping, CNC-machined flanges, robotic welds, and rolled tip options in Titanium or Stainless Steel, the Q300 gives the 86/BRZ platform a polished performance upgrade that works well for daily driving, weekend backroads, and clean street builds.

Key Features

• Refined Performance Sound: Quieter than Invidia’s N1 and R400 systems while still adding a deep, sporty exhaust tone.
• 70mm Piping Diameter: Optimized for improved exhaust flow and reduced back pressure.
• 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 flow with minimal restriction.
• Rolled Exhaust Tips: Clean, finished tip design for a more premium rear appearance.
• 101mm Tip Diameter: Large tips fill out the rear bumper nicely without looking out of place.
• Titanium or Stainless Steel Tip Options: Choose the finish that best matches your build.
• CNC-Machined Flanges: Designed for precise fitment and durability.
• Robotic Welds: Consistent weld quality for strength and clean appearance.

Why We Like It

The Q300 is the Invidia exhaust we like for owners who want a more mature sound profile. It still improves tone and flow over stock, but it keeps volume under control for daily use. If you want something that sounds deeper and more intentional without the louder, more aggressive character of an N1-style exhaust, the Q300 is the better fit.

Sound & Performance

Invidia’s Q300 muffler design is tuned to provide efficient exhaust flow while keeping overall volume more controlled. The result is a rich, deep exhaust note that enhances the natural sound of the FA20 or FA24 engine without adding excessive harshness or unwanted sound qualities.
