Vehicle Fitment

• 2022-2025 Toyota GR Corolla (FWD/AWD, 1.6L Turbo I3 G16E-GTS)

Fitment Notes

• Cat-back exhaust only - does not alter, remove, or replace any emissions equipment
• Connects to the factory downpipe/catalytic converter outlet; verify diameter compatibility if running an aftermarket downpipe

Features

• R400 muffler design uses continuous internal piping with Advantex material for optimized back pressure and deep, aggressive exhaust tone
• 76mm mandrel-bent SUS304 polished stainless steel piping minimizes restrictions and reduces back pressure throughout the power band
• Flat-bottom muffler design aids high-speed aerodynamics and contributes to a rich, deep sporty sound
• CNC-machined cast flanges ensure a stress-free, leak-proof fit at every connection point
• Robotic TIG welding throughout for precision, consistency, and long-term structural integrity
• Rolled titanium exhaust tips (110mm) add a premium, race-inspired underbody appearance
• Improves throttle response, mid-range torque, and top-end power output
• Hardware and gaskets included for straightforward bolt-on installation

Product Description

The Invidia HS22TGCGM2RTL is the R400 cat-back exhaust system designed specifically for the 2022-2025 Toyota GR Corolla. Built around 76mm mandrel-bent SUS304 stainless steel piping, this system replaces the restrictive factory exhaust from the catalytic converter back, opening up exhaust flow to improve throttle response and power delivery across the RPM range. The R400 muffler uses a continuous internal piping design packed with Advantex acoustic material to deliver a deep, aggressive sound profile that's engaging under hard acceleration without excessive drone at highway speeds.

Invidia's construction quality sets this system apart - CNC-machined cast flanges eliminate the flex and micro-leaks common in stamped flange designs, while robotic TIG welding ensures every joint is structurally precise and consistent. The rolled titanium tips measure 110mm and finish the install with a clean, race-inspired aesthetic at the rear bumper. All necessary hardware and gaskets are included for a bolt-on installation.
