Volume is what absorbs sound energy, so cutting the case down means the internal packing and the perforated tube have to do proportionally more, and the welding has less room to hide behind length. Spark builds this one in titanium like the rest of the range, with the case, inner tube and end cap all in the same material.\u003c\/p\u003e\u003cp\u003eThe heat shield matters more here than on a long case, because a short silencer sits closer to the rider's boot on most rearset positions. It comes with the group.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; Sound\u003c\/h2\u003e\u003cp\u003eSpark quotes no decibel figure for the Moto GP case on the R9. On the Honda CBR 1000 RR-R, where it does publish comparative numbers, the Moto GP sits marginally below the Grid-O and above the enclosed road options — a useful indication of where it lands, but not a substitute for a measurement on your own bike. If you are riding a series with scrutineering, ask us before you order.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eFor Spark's Yamaha R9 collectors GYA8801 and GYA8802. The inlet is dimensioned for Spark pipework, so this is not a slip-on for the standard exhaust. The other short option in the range is the Grid-O, G00SI42T; the quiet option is the 400 mm Force Evo, G00SI44T.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNo EC approval.
