Three kilos off the tail of a superbike is the kind of change you feel at turn-in rather than read on a dyno sheet.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStainless steel manifold and link with two Moto GP silencers, underseat.\u003c\/li\u003e\n\u003cli\u003e3.2 kg against 6.2 kg — 3.0 kg removed.\u003c\/li\u003e\n\u003cli\u003eMoto GP is Spark's short, steeply cut prototype-derived case.\u003c\/li\u003e\n\u003cli\u003eCompatible with the original licence plate holder.\u003c\/li\u003e\n\u003cli\u003eWorks with the original fairings and 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\u003eThe Short Case Problem\u003c\/h2\u003e\u003cp\u003eA Moto GP silencer is noticeably shorter than the Grid-O or the rectangular cases in this range, and short silencers are harder to make work. Volume is what absorbs sound energy, so cutting the case down forces the packing and the perforated core to do proportionally more of the job — and leaves the welding much less length to hide behind.\u003c\/p\u003e\u003cp\u003eThe reason to accept that difficulty is the look. On a Panigale V4 the underseat position puts the outlets right under the tail light, and a short case there reads as prototype rather than aftermarket. It is the most compact of the underseat options Spark offers for the bike.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; Sound\u003c\/h2\u003e\u003cp\u003eSpark publishes no decibel figure for this configuration. For context, the other underseat kits on this bike sit between 102 and 105 dB, and the Moto GP case tends to land at the upper end of a range because of its length. If you need a number before entering a series that checks, ask us and we will request it from Spark rather than estimate.\u003c\/p\u003e\u003cp\u003eAn ECU remap is recommended. On a V4 that is not boilerplate — the standard map is written around a restrictive exhaust.\u003c\/p\u003e\u003ch2\u003eStainless Through and Through\u003c\/h2\u003e\u003cp\u003eManifold and link are both stainless on this kit, and that is what puts it at the bottom of the price list for Spark's underseat range. It is also what keeps it there in weight: 3.2 kg is genuinely light for a stainless assembly, and the reason is that the section being replaced — the standard collector and silencers on a Panigale V4 — is unusually heavy to begin with.\u003c\/p\u003e\u003cp\u003eStainless has a second advantage that gets overlooked on a bike like this. The underseat run passes close to the shock and the rear tyre, where a stone thrown up at speed lands with real force. A stainless section shrugs that off; thin titanium dents.\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 the passenger footboard.\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, V4 R (2018-2024) and the Streetfighter V4.
