Exhaust system suitable for Toyota GR Supra A90 - freeing the B58 voice
The GR Supra A90 with the 3.0 litre B58 sounds quieter from the factory than the engine deserves. This collection holds the GRAIL valved system suitable for Toyota GR Supra MK5 (A90) with ECE type approval and Milltek sports exhausts - both developed specifically for the Supra.
ECE approved: no trouble at a roadside check
Thanks to ECE approval the GRAIL system needs no registration entry under German law - fit it and drive legally. The valves run on your Supra's factory control. Anyone who knows the straight-six knows what is possible here: relaxed when closed, properly present when open. More systems: GRAIL overview.
Fitting in Essen - also for long journeys
The work is done in our own workshop in Essen on the proven model: 50% deposit, the rest after fitting. Supra drivers come from all over the country for it - book by WhatsApp, and the job is usually finished the same day.
Frequently asked questions about the GR Supra exhaust
Does the GRAIL system on the GR Supra need a registration entry?
No - it has ECE type approval, so no entry is needed as long as the engine and exhaust of your Supra are otherwise standard.
Does the system fit every A90 with the 3.0 engine?
The system is designed for the GR Supra MK5 3.0 (B58) - if you are unsure about the model year we check the fit using your chassis number.
How does the Supra sound with a valved system?
The B58 gains a distinctly fuller straight-six note - with the valves closed it stays easy to live with, open it sounds like what the engine can actually do.
Can I book the system and the fitting together?
Yes - order with fitting: 50% deposit, installation in Essen, balance after the work.
