An 83 euro insert that decides whether you get through scrutineering. Spark's dB killer for the Multistrada 950 collector is a perforated grid that fits inside the manifold — not inside the silencer.
Key Features
- dB killer with a special perforated grid, for Spark's collector on the Ducati Multistrada 950.
- Installs in the manifold, not in the silencer.
- Stainless steel construction.
- Optional accessory for Spark collector GDU8523.
- Made by Spark in Mantova, Italy.
Where It Goes
Spark states the restriction plainly: only compatible if installed on the manifold. This is not a silencer insert and it will not fit one. It sits inside the collector, ahead of the silencer, and reduces the noise of the whole system from there.
That placement is unusual and it is the reason the part has its own article number rather than being sold as a generic accessory.
The Grid
The insert is a perforated grid rather than a plain tube with a hole in it. Many small openings give a larger total flow area than one restriction of the same acoustic effect, which is why a grid reduces noise with less back pressure than a simple baffle.
Why You Would Order One
Because a circuit has a noise limit at the gate. Spark's collector GDU8523 deletes the catalytic converter, and a system without a converter is loud; this insert brings the figure down without changing anything else on the motorcycle.
It goes in and comes out with hand tools, so the same machine can run quiet on a limited circuit and open on one that is not.
Stainless, Not Titanium
The insert is stainless steel. It sits in the hottest part of the exhaust and gets removed and refitted repeatedly, so a material that tolerates handling and does not gall against the collector wall is the right choice.
What It Does Not Do
It does not make the system road legal. Spark's collector removes the catalytic converter, and a noise insert changes the decibel figure and nothing else. On a public road the system remains a racing part with or without the grid fitted.
Made in Italy
Spark produces the insert in Mantova alongside the collector it belongs to, which is why the fit is exact rather than approximate.
Fitment & Compatibility
Fits Spark's titanium collector GDU8523 for the Ducati Multistrada 950, 2017 to 2018. It does not fit the standard Ducati manifold and it does not fit a silencer.
Road Approval
Not applicable. This is a noise insert for a racing collector; fitting it does not give the system a road approval.
