It is the straightforward way to build one: more room, fewer packaging constraints, easier to make the numbers work.\u003c\/p\u003e\u003cp\u003eSpark took the harder route and kept the exhaust low, where Yamaha put it. That meant fitting a stainless collector, a catalyst and a pre-silencer box into the space under the engine and still finding room for the Grid-O behind it. The bike keeps its own silhouette; only the sound and the throttle response change.\u003c\/p\u003e\u003ch2\u003eOver Two Horsepower, With the Certificate\u003c\/h2\u003e\u003cp\u003eThe performance figure is worth reading carefully: over 2 hp more, with a fuller response across the entire power curve, in the homologated configuration. Not with the db killer out, not on a track map — as delivered and as certified.\u003c\/p\u003e\u003cp\u003eOn a 73 hp twin, two horsepower is a real percentage. The more useful part is the mid-range: the pre-silencer box was designed as a tuned volume, not just a noise-reduction chamber.\u003c\/p\u003e\u003ch2\u003eThe Box, and the Voice\u003c\/h2\u003e\u003cp\u003eThe silencing box is what makes the low-mount layout possible and what shapes the sound. Spark designed it to bring out the CP2 twin's particular voice — deep, dark and assertive rather than loud.\u003c\/p\u003e\u003cp\u003eThe MT-07 engine has always sounded better than its price suggests. This system is built to make that audible without pushing the bike outside the noise rules.\u003c\/p\u003e\u003ch2\u003eDetails You Will Look At\u003c\/h2\u003e\u003cp\u003eThe titanium mesh of the Grid-O develops intense blue hues as it heats, which is a property of the material rather than a coating — it deepens over the life of the exhaust. The TIG welds on the collector are left visible for the same reason: they are the part of the article that shows how it was made.\u003c\/p\u003e\u003ch2\u003eEuro 5+, and the Euro 5 Bikes Too\u003c\/h2\u003e\u003cp\u003eThe system is homologated to Euro 5+ and remains fully compatible with the previous Euro 5 versions of these motorcycles. One article number covers the platform from 2021 forward, which is unusual and is worth knowing if you are buying for an earlier bike.\u003c\/p\u003e\u003ch2\u003eOne Note for R7 Owners\u003c\/h2\u003e\u003cp\u003eOn the 2026 R7 the lower fairing must be removed to fit this system. Spark states it and we repeat it here, because it is the kind of detail that turns a straightforward installation into an argument on a Saturday afternoon.\u003c\/p\u003e\u003cp\u003eOn the MT-07, the XSR700 and the Tracer there is no such requirement.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha MT-07, R7, Tracer 7 and XSR700, 2021 to 2026, including the Euro 5 versions. This is a full system: the original headers, catalyst and silencer all come off. Spark's page and the dealer price list describe the same article under different bikes — the list files it under the MT-07\/XSR700 and the Tracer 7, Spark's own page adds the R7.
