YAMAHA D-Plate & Cat Temp Sensor Chip Kit with Gaskets Catalytic Converter Delete Kit for Yamaha Waverunner 2-Stroke Models
Replace your restrictive catalytic converter with our high-quality stainless steel D-Plate — a direct, low-cost alternative that Yamaha originally used in non-catalytic markets.
Kit Includes:
- 1 × Stainless Steel D-Plate
- 1 × Cat Temperature Sensor Chip
- 2 × Exhaust Gaskets
Fits the following models:
- GP1200R (2000–2003)
- GP1300R (2003–2004)
- XL1200 / XL1200 LTD
- XLT1200 / XLT1200 LTD
Key Benefits:
- Lower engine bay temperatures — significantly reduces heat buildup around the engine.
- Increased performance — removes the restrictive cat for better exhaust flow and more power.
- Freedom to run regular TCW-3 2-stroke oil — no longer restricted to expensive Yamaha-spec oil.
- Includes the Cat Temp Sensor Chip, which perfectly mimics the original catalytic converter temperature signal. This prevents CDI errors, warning lights, fluttering, or engine shutdowns on models with OEM CDI.
Important Note: This modification affects emissions output. It is intended for competition / off-road use only and is not legal for use on public waterways where emissions compliance is required. Check local regulations before installing.
This kit is a proven, popular upgrade among GP1200R and GP1300R owners looking for a simple, reliable cat delete solution without the high cost of aftermarket full exhaust systems.
Easy bolt-on installation — includes everything needed for a clean, leak-free fit.
