That is the entire difference between this manifold and the STEP1 below it, and Spark charges exactly the same for it — which makes the choice between them a question about the engine rather than about money.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStainless steel 3\/4 manifold at 60 mm for the Yamaha R1 and R1M.\u003c\/li\u003e\n\u003cli\u003eSTEP2 of Spark's three-diameter range: D.54, D.60, D.65.\u003c\/li\u003e\n\u003cli\u003eSame list price as the D.54 STEP1 manifold.\u003c\/li\u003e\n\u003cli\u003eDeletes the catalytic converter.\u003c\/li\u003e\n\u003cli\u003eTakes the D.60 silencer groups, including the Force with dB killer.\u003c\/li\u003e\n\u003cli\u003eSupplied without a silencer.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eChoosing Between D.54 and D.60\u003c\/h2\u003e\u003cp\u003eSince the two cost the same, Spark's own answer is the one to use, and it is about model years rather than budget: the D.54 was the first version, optimised for the 2015-2019 R1, and Spark notes it allows an even lower decibel reading. The D.60 is the system optimised for 2020-2023, matched to a silencer with a 60 mm inlet.\u003c\/p\u003e\u003cp\u003eBoth fit the whole 2015-2025 range mechanically, so the choice is real either way. If your bike is a later one, or if the circuits you ride do not measure at the gate, the D.60 is the diameter Spark designed around it.\u003c\/p\u003e\u003ch2\u003eWhere This Sits in the Range\u003c\/h2\u003e\u003cp\u003eSpark's R1 programme reads as a ladder and the rungs are diameters. D.54 and D.60 are 3\/4 systems: the standard headers stay, the section behind the collector is replaced, the catalytic converter comes out. D.65 is where the headers go too, and where the price roughly triples.\u003c\/p\u003e\u003cp\u003eBuying the D.60 manifold on its own puts you on the middle rung with a silencer of your choosing. It is also the diameter with the widest silencer selection on this bike — five different cases, including the one supplied with a removable dB killer for circuits that measure at the gate.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha R1 and R1M, 2015 through 2025.
