One splits into a pair of silencers under the tail; this one gathers everything into a single Force Evo case. The collector is what makes that difference — the pipework, not the silencer, decides which layout a bike ends up with.\u003c\/p\u003e\u003cp\u003eIt is also why the two are not interchangeable. A 2-1 collector will not feed a 2-1-2 kit and the reverse is equally true.\u003c\/p\u003e\u003ch2\u003eAISI 304, Welded by Hand\u003c\/h2\u003e\u003cp\u003eStainless rather than titanium. On the complete kit that puts the weight at 4.9 kg against 6.4 for the standard exhaust — the same figure Spark quotes for the titanium 3\/4 kit, because on this motorcycle the weight comes out of the layout more than out of the material.\u003c\/p\u003e\u003cp\u003eWhat stainless does buy is durability. It takes a knock, it takes a re-weld, and it does not mind being removed and refitted between sessions. All the seams are TIG-welded by hand.\u003c\/p\u003e\u003ch2\u003e104 dB, Not 102\u003c\/h2\u003e\u003cp\u003eSpark rates this kit at 104 dB, against 102 for the rectangular-silencer version. That two-decibel gap sounds trivial and is not: circuits that publish a 102 limit will turn away a bike that reads 104 at the static test.\u003c\/p\u003e\u003cp\u003eIf the machine runs at events with a hard 102 dB rule, the collector to look at is GDU8838 with the rectangular kit. If the limit is 105 or there is none, this is the layout with the single case.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eA 3\/4 kit keeps the original collectors from the cylinder heads and replaces the section behind them, which is what this article is. Spark states compatibility with the original fairings and with closed fairings for racing use.\u003c\/p\u003e\u003cp\u003eOn Euro5 machines the plastic cover of the standard collector needs a few millimetres filed off before the Spark part seats correctly.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eDucati Panigale V4, V4 S and V4 R, 2018 to 2024, and Streetfighter V4, 2020 to 2024, as listed by Spark for this collector.
