The Injen Race Series cat-back exhaust for 2020–2023 Toyota GR Supra 3.0L Turbo (SES2300RS) is a single-exit, full-length 3.50-inch tubing system engineered to replace factory mufflers, resonators, and valves for a race-inspired tone and reduced weight. It uses V‑band clamps and factory mounting points for straightforward installation, is TIG‑welded from stainless steel, and is dyno-proven to add roughly 10 HP and 11 lb‑ft at the wheels.
