Injen Toyota Supra exhaust system - SMINKpower Performance Parts



The Injen Technology Performance Cat-Back Exhaust System for the 2020-2021 Toyota GR Supra equipped with the L6-3.0L Turbo was designed from the ground up to compliment the aggressive styling and blistering performance of these sporty coupes. In addition, Injen Technology’s custom dual muffler design hones the engine’s tone into an ear-pleasing symphony. This dual muffler design purposefully delivers a crisp, clean, deep rumble at idle and an aggressive roar when pushing the car’s limits. Massive 3.50in (89mm) tubing makes up the front and mid-section, while the rear section is constructed of huge 3.00in (76mm) tubing. The premium polished finish on the mufflers is sure to impress anyone curious enough to take a look at the undercarriage and the beautiful 4.5in (114mm) carbon fiber exhaust tips offer superb aesthetics that perfectly compliment the sound of the system itself.

Injen Technology included an exhaust valve that utilizes the stock motor (not included). Once the driver switches to Sport mode, the true level of performance and sound this exhaust provides will be achieved. Outstanding flow from the 3.5in tubing will let that turbo breathe, and the open exhaust valve will deliver an aggressive, throaty, crackling exhaust tone that will keep drivers smiling from ear to ear.

Injen Technology designs every performance product with ease of installation in mind, and this exhaust is no different. On the SES2300CF, Injen Technology has included V-Band clamps and flanges for the most uncomplicated, quickest installation possible. No need for any cutting, drilling, or modification of the vehicle to complete installation. The system uses all factory mounting points for simple and convenient placement and compatibility. To increase performance, Injen Technology opted for a stepped piping design that keeps the flow rate consistent throughout the length of the exhaust. Keeping the flow rate consistent adds performance and helps keep the tone of the exhaust where Injen Technology designed it to be throughout the rev range.
