Length is the one variable in a silencer that a rider can change after the fact without touching anything else on the motorcycle.\u003c\/p\u003e\u003cp\u003eWhat it costs is a slightly heavier tail and a case that reaches further past the seat unit. What it buys is margin at a sound check. On a bike whose collector is already fixed, swapping between a 350 and a 400 is the only meaningful sound adjustment left that does not involve a plug in the outlet.\u003c\/p\u003e\u003ch2\u003eTwo Cases, One Bike\u003c\/h2\u003e\u003cp\u003eBecause this is the bare silencer, and because it uses the same interface as the shorter case, it makes sense as a second silencer rather than only a replacement.\u003c\/p\u003e\u003cp\u003eCircuits do not publish their noise policy in a single standard, and a limit that is comfortable at one venue is marginal at the next. Keeping both lengths in the van removes that from the list of things to worry about on the morning of a track day, at a cost well below what a second complete system would run to.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha R1 and R1M, 2015 through 2025, on Spark's D.65 STEP2 collectors GYA8880R in titanium or GYA8881R in stainless.
