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
For the most dramatic exhaust note upgrade on your Toyota GR Yaris Gen 2, look no further than this Milltek Sport Non-Resonated OPF/GPF Filter-Back System. Engineered for the updated 2024-onwards GR Yaris, this 76mm (3") stainless steel system bypasses the factory resonator for a louder, more uninhibited exhaust sound that makes the 1.6T feel every bit as dramatic as it looks.
The non-resonated configuration delivers a raw, characterful tone on acceleration with a satisfying bark on each upshift. This is the choice for drivers who want the maximum acoustic transformation from a filter-back system — a proper performance exhaust sound without the need for a full system replacement. Available in five tip finishes, including Brushed Titanium and Burnt Blue Titanium options available exclusively for the Gen 2.
A bolt-on replacement for the factory exhaust system with no cutting, welding, or remapping required. Manufactured in the UK from 304L aircraft-grade stainless steel and E-marked for road use throughout the UK and Europe.
Fitment: Toyota GR Yaris 1.6T (OPF/GPF Models Only) 2024 onwards
Pipe diameter: 76.20mm (3")
Tip options: Polished, Cerakote Black, Brushed Titanium, Burnt Blue Titanium, Carbon Fibre
E-marked: Yes (ECE approved)
Direct OEM replacement — no modifications required
