It is a styling claim and Spark treats it as one — the technical argument is elsewhere.\u003c\/p\u003e\u003cp\u003eThat argument is the volume. The case is sized so the silencer meets the noise level imposed on British circuits, which is what made it the specification for a one-make championship run inside the BSB.\u003c\/p\u003e\u003ch2\u003eTitanium All the Way Through\u003c\/h2\u003e\u003cp\u003eNot just the visible sleeve. Spark states that the inner end cap is titanium as well, which is where a lot of silencers quietly use steel because nobody sees it. On a 400 that runs to five figures of rpm, mass at the far end of the system is the mass that matters least to a spec sheet and most to how the bike changes direction.\u003c\/p\u003e\u003ch2\u003eThe dB Killer Is a Separate Article\u003c\/h2\u003e\u003cp\u003eWorth reading twice: Spark does not put the removable insert in this box. It is article G9999 and has to be ordered alongside.\u003c\/p\u003e\u003cp\u003eIf your events run a static test, order both together. Arriving at scrutineering with a silencer that has nowhere to take an insert is an expensive way to learn the difference.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eKawasaki ZX-4RR, 2023 to 2026.
