Milltek GPF / OPF Bypass with Sports Cat SSXTY134 – Toyota GR Yaris

Milltek Sport Large-Bore Downpipes are perfect when looking to improve both performance and sound. These downpipes are fabricated with a larger diameter than standard OEM parts, meaning that there is significantly more space for more gas to exit the engine and pass through, increasing efficiency.

Combined with the Hi-Flow Sports Cat, you can expect a significant increase in performance and a noticeable difference in sound aesthetic.

From late 2018, many vehicles have been manufactured with a Gasoline/Otto Particulate Filter to further reduce the emissions from the vehicle. The Milltek Sport Particulate Filter-Back range is designed to compensate for the sound reducing qualities from the particulate filter and significantly improve the sound aesthetic of the exhaust system

All products are made from 304L “Aircraft” Grade stainless steel. This quality material will ensure that your system will last through any harsh conditions and is less susceptible to discolouration.

Mandrel bending ensures constant radius bends for optimised gasflow, and bore diameters are carefully enlarged over stock to ensure ultimate performance without the loss of mid-range torque. All of the Milltek exhaust systems endure a comprehensive acoustic development process to deliver a tone that is sporty and crisp, without ever inducing NVH, drone or cabin resonance.

All performance exhaust systems are designed with you in mind, and they cater to an ever-expanding range of vehicles. Milltek believe in continuous evolution, and their research & development team work throughout the year to deliver the most in demand solutions to all your performance exhaust requirements.

All Milltek Sport exhausts are designed, developed and manufactured in-house in the UK.

Please Note: Requires Stage 2 ECU Remap
