One decibel over standard with the insert in place is a very small change for a system that is not homologated — and it tells you that what this kit changes is the character of the sound rather than only its volume. Manufacturers rarely publish the figure their product has to beat.\u003c\/p\u003e\u003ch2\u003eThe Remap Is Not Optional\u003c\/h2\u003e\u003cp\u003eSpark states it directly: the 3\/4 kit removes the original catalytic converter, so it is not homologated and it is necessary to remap the ECU. The company also recommends that a professional mechanic or tuner carries out the installation.\u003c\/p\u003e\u003cp\u003eOn a Ducati V2 that is not a formality. Removing the converter changes what the lambda sensors see, and an engine left to run on the standard map will run lean under load. Budget the remap into the purchase rather than treating it as something to arrange later.\u003c\/p\u003e\u003ch2\u003eWhat the Box Buys\u003c\/h2\u003e\u003cp\u003eThe pre-silencer box is AISI 304 stainless with a TIG-welded segmented fitting, and Spark's description of what it does is worth quoting: it replaces the original bulky exhaust and gives the bike a dark and deep voice without being too loud.\u003c\/p\u003e\u003cp\u003eThat is the reason the readings stay close to standard. A racing 3\/4 system without an expansion chamber ahead of the silencer would be a great deal louder. Spark also claims a large increase in torque throughout the acceleration curve rather than a peak figure — which is the more useful claim on a twin.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eDucati Panigale V2 955 and Streetfighter V2 955, 2020 through 2024, and the Panigale 959 from 2016 through 2019.
