A direct bolt-on replacement for the factory cat-back with no cutting, welding, or modifications required.

Invidia R400 – Top-Tier Performance Line

The R400 sits at the top of Invidia’s cat-back lineup — above the N1 and N2 series. Here’s how the Invidia lines compare for the GR Corolla:

• R400 (this system): Invidia’s highest-flow, most aggressive cat-back line. Larger piping, higher-flow construction, and the most aggressive exhaust note in the Invidia lineup. Best for performance-focused builds and track use where maximum flow and sound are the priority
• N1: Performance cat-back with aggressive sound — a step below the R400 in flow and volume. Strong street and track choice
• Q300: Dual-layer construction for a quieter, more refined tone. Best for daily drivers who want an exhaust upgrade without maximum volume

Key Features

• R400 High-Flow Construction – Maximum Cat-Back Performance: R400-spec piping and construction delivers Invidia’s highest flow rate in the cat-back lineup — reducing back pressure and improving exhaust gas evacuation from the G16E-GTS’s turbocharged 3-cylinder for improved power delivery and throttle response, particularly in the mid-to-upper RPM range where exhaust flow restriction has the greatest impact on turbocharged performance
• Rolled Titanium Tip – Premium Finish: Invidia rolled titanium exhaust tip — a premium, race-inspired finish that develops a natural heat-blued patina over time. The rolled edge tip profile is a signature Invidia aesthetic detail. Titanium tip is lightweight and corrosion-resistant
• Aggressive Exhaust Note – G16E-GTS Character: The R400 enhances the G16E-GTS’s turbocharged 3-cylinder exhaust character — delivering a more aggressive, higher-volume exhaust note than the factory system. The 3-cylinder firing order gives the GR Corolla a distinctive exhaust pulse character that the R400 amplifies
• Cat-Back – Emissions Friendly: Cat-back system replaces the exhaust from the catalytic converter rearward — factory catalytic converter is retained, making this system emissions-friendly in most jurisdictions. Verify local regulations before purchasing

Uses factory mounting points and includes all necessary gaskets and hardware. No cutting, welding, or modifications required. Verify your specific model year and trim before ordering

Note: Titanium tip will develop a heat-blued patina over time — this is a natural characteristic of titanium, not a defect. Professional installation recommended. Apply anti-seize to all fasteners during installation. Check for exhaust leaks after the first heat cycle. Check local noise and emissions regulations before purchasing — aftermarket exhausts may not be street-legal in all jurisdictions.
