Twin Dyno silencers on a titanium collector give 102 dB at 5,500 rpm with nothing fitted — and with the optional dB killers in place the reading drops below 100 dB. That is a number that gets you onto almost any European track.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTitanium collector with two Dyno silencers in the underseat position.\u003c\/li\u003e\n\u003cli\u003e102 dB at 5,500 rpm without dB killers; below 100 dB with the optional dB killers fitted.\u003c\/li\u003e\n\u003cli\u003e3.4 kg against 6.4 kg for the section it replaces — 3.0 kg saved.\u003c\/li\u003e\n\u003cli\u003eDyno is Spark's sculpted case — the company calls it pure design, technology and precious details.\u003c\/li\u003e\n\u003cli\u003eWorks with the original number plate holder and standard or closed racing bodywork.\u003c\/li\u003e\n\u003cli\u003ePanigale V4, V4 S, V4 R and Streetfighter V4.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuilt Around a Number\u003c\/h2\u003e\u003cp\u003eMost exhausts are designed and then measured. This one was designed to hit a figure. Spark states the reason plainly: international circuits impose ever stricter decibel requirements, so the company introduced a version that reaches the track at maximum performance while staying within 102 dB at 5,500 rpm. The dB killers take it under 100 dB when a specific event demands it.\u003c\/p\u003e\u003cp\u003eIf you have ever been sent home by a noise meter, that combination — a race exhaust with a documented sub-100 dB configuration — is worth more than a few tenths of a second.\u003c\/p\u003e\u003ch2\u003eBuild Quality \u0026amp; Materials\u003c\/h2\u003e\u003cp\u003eTitanium collector, twin Dyno silencers with carbon end caps. The Dyno case is the most heavily worked shape in Spark's catalogue; the company describes it as a piece of jewellery for the bike, which is marketing language for a case that costs more to form than a plain cylinder.\u003c\/p\u003e\u003cp\u003eOne care note from Spark that applies to all its cases: wash with water and rinse. No degreasers, no car-wash chemicals.\u003c\/p\u003e\u003ch2\u003eHow the Numbers Are Taken\u003c\/h2\u003e\u003cp\u003eTwo details matter when you compare decibel figures. The first is engine speed: Spark quotes 102 dB at 5,500 rpm, and a figure taken at a different rpm is not comparable. Most European static noise tests specify a speed derived from the engine's maximum power point, so ask which one your series uses before assuming a published number will clear it.\u003c\/p\u003e\u003cp\u003eThe second is the dB killer. It is a removable restrictor that sits in the outlet and trades a little flow for several decibels. Spark states this kit falls below 100 dB with them fitted — a meaningful margin at a circuit enforcing 100 dB, and the reason this is the kit to buy if your calendar includes tracks you have not measured at yet.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eECU mapping is recommended.\u003c\/li\u003e\n\u003cli\u003eCompatible with the original fairings and with closed fairings for racing use.\u003c\/li\u003e\n\u003cli\u003eCompatible with the original licence plate holder.\u003c\/li\u003e\n\u003cli\u003eNot compatible with passenger footboards.\u003c\/li\u003e\n\u003cli\u003eThe under-saddle lock is not accessible once fitted.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eDucati Panigale V4, V4 S and V4 R (2018-2024) plus the Streetfighter V4.
