Unleash the full acoustic potential of your Toyota GR Yaris Gen 1 with this Milltek Sport Non-Resonated OPF/GPF Filter-Back System. Removing the factory resonator gives this system a louder, more aggressive exhaust note that truly reflects the GR Yaris's motorsport DNA. Constructed from 76mm (3") diameter stainless steel tubing, this system significantly reduces back pressure through the OPF/GPF section for improved exhaust gas evacuation.
The non-resonated design produces a full, characterful exhaust tone that's particularly impressive under acceleration. For enthusiast drivers who want the most dramatic sound improvement without touching the OPF/GPF itself, this is the definitive choice. Available in five tip finishes to perfectly complement your GR Yaris.
A direct bolt-on replacement for the factory exhaust — no cutting, welding, or ECU remapping required. An optional remap will further maximise performance, but this system transforms the sound and feel of the car straight out of the box. Manufactured from 304L aircraft-grade stainless steel at Milltek Sport's UK factory.
Fitment: Toyota GR Yaris & GR Yaris Circuit Pack 1.6T (OPF/GPF Models Only) 2020–2024
