Spark's 3\/4 kit replaces everything from the mid-section back with a titanium collector and two Grid-O silencers that sit where the factory ones do — except these weigh 3.3 kg against 6.4 kg, and they are meant to be seen.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTitanium collector with two Grid-O silencers in the underseat position.\u003c\/li\u003e\n\u003cli\u003e3.3 kg against 6.4 kg for the section it replaces — 3.1 kg saved.\u003c\/li\u003e\n\u003cli\u003eMeasured by Spark at 105 dB.\u003c\/li\u003e\n\u003cli\u003eKeeps the standard tail and works with the original number plate holder.\u003c\/li\u003e\n\u003cli\u003eCompatible with both the original fairings and closed racing bodywork.\u003c\/li\u003e\n\u003cli\u003eA removable dB killer can be fitted to either silencer.\u003c\/li\u003e\n\u003cli\u003eFits the Panigale V4, V4 S, V4 R and the Streetfighter V4.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy Underseat Is Harder\u003c\/h2\u003e\u003cp\u003eAn underseat exhaust has to route two silencers through the tightest part of the motorcycle, clear the shock and the subframe, and still get rid of its heat without cooking the seat. That is why Spark builds this as a kit rather than a slip-on: the collector geometry, the link routing and the silencer position are one design decision, not three.\u003c\/p\u003e\u003cp\u003eThe Grid-O silencers are the same design Spark runs on Moto2 and Superbike grids — titanium throughout, mesh end caps, weld seams left visible rather than polished away.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; Sound\u003c\/h2\u003e\u003cp\u003e105 dB without a dB killer. That sits between the 102 dB Dyno kit and the 112 dB lateral Grid-O version, and it is the figure most European circuits will accept without argument. Both silencers take a removable dB killer if you need to go lower for a specific event.\u003c\/p\u003e\u003cp\u003eSpark recommends an ECU remap. On a V4 that is not a formality — the standard mapping is written around a restrictive exhaust, and leaving it alone gives away most of what the kit is for.\u003c\/p\u003e\u003ch2\u003eWhat a 3\/4 Kit Actually Replaces\u003c\/h2\u003e\u003cp\u003eThe name confuses people, so here it is plainly. A full system replaces everything from the cylinder heads back. A 3\/4 kit leaves the primary headers on the engine and replaces the collector, the link section and both silencers. On a Panigale V4 that matters because the headers are buried behind the fairing and the front wheel, and getting them out is a genuinely awkward job.\u003c\/p\u003e\u003cp\u003eThe practical consequence: you keep the standard lambda sensor positions and the standard header geometry, you fit the kit in an evening rather than a weekend, and you still get the collector — which is where most of the flow restriction lives. It is the point where cost, effort and result cross most usefully for a bike that is not a full race machine.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eSpark's own notes:\u003c\/p\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 no longer accessible with this kit 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) and the Streetfighter V4.
