This decat GPF delete pipe is designed to improve exhaust gas flow and engine performance on the Toyota GR Yaris 1.6 Turbo (2020–2024).
The pipe replaces the standard GPF filter with a freer-flowing design, reducing exhaust back pressure and allowing exhaust gases to flow more efficiently.
Featuring a 4" to 3" design, the pipe is manufactured from mandrel-bent T304 stainless steel for strength and corrosion resistance. Its smooth-flowing construction is designed to support increased power output and future performance upgrades.
An integrated flexi section helps reduce stress on the rest of the exhaust system, while TIG-welded construction and CNC-machined flanges ensure accurate fitment.
