Termignoni Decat Pipe Yamaha YZF-R1 2009-14

Race-ready exhaust flow upgrade for the Yamaha YZF-R1

The Termignoni Decat Pipe for the Yamaha YZF-R1 2009–2014 is designed to maximise exhaust flow and unlock the full performance potential of Yamaha’s superbike engine. By removing the restrictive catalytic converter, this stainless steel mid-pipe improves throttle response, reduces weight and delivers a more aggressive exhaust tone.

Manufactured from high-quality stainless steel, this precision-engineered decat section integrates seamlessly with both the original exhaust silencer and compatible aftermarket systems. A lambda sensor port is included for correct engine management, along with a blanking plug for applications where the sensor is not required.
