The standard R6 exhaust weighs 10.3, so Spark's STEP 3 kit with the Grid-O silencer takes just under seven kilos off a 600 — and almost all of it from the middle and the right-hand side of the motorcycle.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull titanium racing system for the Yamaha R6 and YZF-R6 Race.\u003c\/li\u003e\n\u003cli\u003eTitanium collector with Grid-O silencer.\u003c\/li\u003e\n\u003cli\u003eSTEP 3: Spark's latest kit level, connections machined from solid by CNC.\u003c\/li\u003e\n\u003cli\u003e3.4 kg against 10.3 kg for the standard system.\u003c\/li\u003e\n\u003cli\u003eThe lightest of Spark's three STEP 3 builds for this motorcycle.\u003c\/li\u003e\n\u003cli\u003eRacing part, not approved for road use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSTEP 1, 2 and 3\u003c\/h2\u003e\u003cp\u003eSpark numbers its R6 kits, and the numbers mean something specific. STEP 1 was the first version — cheaper, and without the CNC connections. STEP 2 added those connections, improving how the collector sections couple and how long they stay tight, and brought a torque gain in the mid-range. STEP 3 is the latest, developed specifically around engines in Supersport configuration, and it keeps the machined-from-solid joints.\u003c\/p\u003e\u003cp\u003eIf you are comparing offers on a used system, the step level is worth more than the silencer badge. A STEP 1 and a STEP 3 are not the same exhaust with a different case on the end.\u003c\/p\u003e\u003ch2\u003eSix Point Nine Kilos\u003c\/h2\u003e\u003cp\u003eThe weight is where this kit separates itself, including from its own siblings: the Konix Evo build is 4.0 kg and the Force Evo 4.2, against 3.4 here. On a motorcycle that weighs under 190 kilos dry, seven kilos out of the exhaust is a change you feel turning in, not a number for the spec sheet.\u003c\/p\u003e\u003cp\u003eThe Grid-O case is the reason. It is the lightest silencer Spark makes — a perforated titanium sleeve with a mesh end cap, laser-cut and TIG-welded, with no clamped rings adding mass at either end.\u003c\/p\u003e\u003ch2\u003eNo Noise Figure, and What That Means\u003c\/h2\u003e\u003cp\u003eSpark quotes 102 dB for the Force Evo version of this kit and 106 dB for the Konix Evo. For the Grid-O it quotes nothing, which is the honest signal: this is the configuration for riders with no static limit to meet, or with a limit high enough not to think about.\u003c\/p\u003e\u003cp\u003eIf your circuit publishes a hard number, take the Force Evo build, GYA8873T. If it does not, this is the lighter and cheaper of the two.\u003c\/p\u003e\u003ch2\u003eWhat the Kit Has Won\u003c\/h2\u003e\u003cp\u003eSpark developed the R6 system with riders and teams over several seasons and took the Italian SSP600 title with it in 2019 and again in 2020. At the opening round of that championship the system recorded the top speed of the meeting at Mugello, 275.50 km\/h.\u003c\/p\u003e\u003cp\u003eThose are the manufacturer's figures and they describe a race bike, not a road one — but they do tell you what the collector was optimised against.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eFull system: the standard collector comes off and Spark's replaces it entirely. The STEP 3 connections are machined from solid on a CNC, which is what makes the collector joints repeatable when the system is taken apart between sessions.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha R6 and YZF-R6 Race, 2006 to 2026.
