Unlock the true acoustic and performance potential of your 1.6L turbocharged 3-cylinder with the Garage Whifbitz 3" Stainless Steel OPF/GPF Delete Pipe. Designed specifically for the Toyota GR Yaris, this premium bypass pipe is the ultimate solution for removing the highly restrictive factory Otto Particulate Filter (OPF) / Gasoline Particulate Filter (GPF).
By replacing the bulky factory filter with the high-flow 3-inch section, you drastically reduce exhaust backpressure. The result? Faster turbo spool, increased power delivery across the rev range, and a much-needed aggressive, deep exhaust note that the GR Yaris deserves from the factory.
Key Features & Specifications:
Premium T304 Stainless Steel Construction: Built to withstand intense heat and resist corrosion, ensuring long-term durability under harsh track conditions.
High-Flow 3" (76mm) Bore: Optimal piping diameter maximizes exhaust gas velocity and flows significantly better than the restrictive stock unit.
Mandrel-Bent Tubing: Ensures smooth, uniform inner walls with zero restrictions or airflow turbulence.
Direct Bolt-On Fitment: Engineered as a direct replacement for the factory GPF/OPF section, utilizing OEM mounting points for a hassle-free installation.
Resonated or Non-Resonated Options: Choose Resonated for a deeper, tuned exhaust note with minimal cabin drone, or Non-Resonated for maximum raw sound volume and a more aggressive track presence.
Track & Off-Road Disclaimer: This product is designed, manufactured, and sold for Off-Road / Motorsport Track Use Only. Removing a factory-fitted emissions component like a GPF/OPF means this vehicle will not comply with UK/EU road regulations or pass standard MOT emissions testing. It is not intended for public highway use.
