Termignoni De-Cat Pipe for Ducati Panigale 959 (2016-2019) D16909430IXX

Removing the factory catalyst is one of the most accessible and rewarding bolt-on upgrades available for the Ducati Panigale 959. The Termignoni D16909430IXX de-cat pipe replaces the restrictive OEM catalyst section with a straight-through stainless steel tube, freeing up exhaust flow, sharpening throttle response and letting the 959 breathe the way it was always meant to — without the weight or backpressure penalty of the stock unit.

Key Features

• Direct OEM replacement: engineered specifically for the Ducati Panigale 959 (2016-2019), ensuring a precise, hassle-free fit with no fabrication or modification required.
• Stainless steel construction delivers long-term resistance to corrosion and heat cycling, so the investment holds up through daily use and track days alike.
• Eliminates catalyst backpressure to improve exhaust scavenging, translating to crisper throttle pick-up and more linear power delivery across the rev range.
• A cost-effective performance step — the de-cat pipe works with the existing headers and silencer, maximising the value of your current exhaust setup.
• Clean, factory-quality finish that sits neatly within the original exhaust routing, maintaining the bike's visual lines.

Performance and Everyday Usability

The Termignoni de-cat pipe strikes a practical balance between outright performance and real-world usability. By replacing the heavy, flow-restricting catalyst with a free-flowing stainless steel section, the Panigale 959 gains a noticeably sharper response to the throttle — particularly useful in urban traffic where clean, predictable fuelling makes riding less tiring. On a back road or circuit, the improved exhaust scavenging allows the engine to breathe more efficiently at higher rpm, supporting stronger mid-range and top-end performance.

Because this is a bolt-on component designed to Termignoni's exact fitment tolerances, installation is straightforward and requires no specialist tools beyond a standard workshop set. The stainless steel tube is built to withstand repeated heat cycles without warping or corroding, keeping maintenance demands low even for riders who cover significant mileage year-round.

Build Quality

Termignoni is one of the longest-established names in Italian exhaust engineering, supplying both homologated road systems and outright racing components. The D16909430IXX is manufactured to the same quality standards as the brand's full exhaust systems: precision-formed stainless steel tube, consistent weld quality and tight dimensional tolerances that guarantee a leak-free seal at every joint.

Fitment and Compatibility

This de-cat pipe is designed exclusively for the following motorcycle:

• Ducati Panigale 959 — model years 2016, 2017, 2018 and 2019

Always confirm your frame number and model year before ordering. Note that removing the catalyst affects emissions compliance; check local regulations and consider whether an ECU remap is advisable to optimise fuelling for the open exhaust path.
