Wagner Tuning Toyota Supra

Downpipe kits are the core of the current GR Supra range. The catted kit uses a 200CPSI catalyst, while the catless kit deletes the catalyst entirely. Check each product page for pipe sizing and included hardware.

Match your car by chassis code first. Wagner Tuning lists these downpipes for the A90 GR Supra. If you are unsure of your chassis code, check your build plate or compliance plate, and confirm engine variant before ordering. Catless components are described by the manufacturer as intended for off-road or motorsport use and may not be legal for road use in your state or territory.

Downpipe fitment generally requires the vehicle to be safely raised, removal of underbody panels and the factory downpipe section, plus new gaskets and fasteners where specified. Oxygen sensor handling and post-fitment tuning may also be required. Installation by a qualified professional workshop is recommended.

Will these fit the A90 GR Supra? The products in this collection are listed by Wagner Tuning for the Toyota GR Supra (A90). Confirm your chassis code and variant before purchase.

What is the difference between catted and catless? The catted kit retains a 200CPSI catalyst, while the catless kit has no catalyst. Emissions rules differ by state and territory.

Do I need a tune? Exhaust changes commonly require an ECU calibration. Speak with your tuner about what suits your setup.
