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.\u003c\/p\u003e\u003cp\u003eThat placement is unusual and it is the reason the part has its own article number rather than being sold as a generic accessory.\u003c\/p\u003e\u003ch2\u003eThe Grid\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch2\u003eWhy You Would Order One\u003c\/h2\u003e\u003cp\u003eBecause 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.\u003c\/p\u003e\u003cp\u003eIt 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.\u003c\/p\u003e\u003ch2\u003eStainless, Not Titanium\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch2\u003eWhat It Does Not Do\u003c\/h2\u003e\u003cp\u003eIt 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.\u003c\/p\u003e\u003ch2\u003eMade in Italy\u003c\/h2\u003e\u003cp\u003eSpark produces the insert in Mantova alongside the collector it belongs to, which is why the fit is exact rather than approximate.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eFits Spark's titanium collector GDU8523 for the Ducati Multistrada 950, 2017 to 2018.
