String Theory Garage will be closed to the public from Wednesday, 29th July to Thursday, 6th August for our annual shutdown.
If you need to get in touch, please leave us a voicemail or send an email. Our team will happily get back to you when we return on Friday, 7th August.
Shopping online? Don't worry! Our online store will remain active! We hope to ship orders placed for in-stock items as normal during the shutdown. Anything else will be dealt with upon our return.
Thank you for your understanding, String Theory Garage Team
The ultimate exhaust upgrade for the Toyota GR Yaris Gen 2 — the Milltek Sport Valved Straight Pipe System with Polished GT-115 Tips. ECE approved and road-legal, this system puts full electronic control over your exhaust note at your fingertips, switching seamlessly between a civilised road tone and a full, unrestricted straight-pipe sound on demand.
The electronically controlled valve system integrates directly with the GR Yaris Gen 2's CAN bus, enabling a factory-quality installation with no additional switches or controllers required. Open the valves for a truly exhilarating straight-pipe note that unleashes the character of the 1.6T; close them when refinement is called for.
Finished with classic polished GT-115 tips and manufactured from 304L aircraft-grade stainless steel in the UK, this is Milltek Sport's flagship GR Yaris Gen 2 system in its most timeless and elegant finish.
Fitment: Toyota GR Yaris Gen 2 – 1.6T OPF/GPF Models (2024 and later)
