The company states its R\u0026amp;D department worked for months to produce headers specifically designed and dimensioned to optimise the performance of the new unit.\u003c\/p\u003e\u003cp\u003eThat is the correct answer and an expensive one. Primary length and diameter determine where a four-cylinder's pressure waves arrive relative to valve timing, and an engine with revised timing wants different numbers. Carrying over the previous system would have worked and given away most of what a full system is bought for.\u003c\/p\u003e\u003ch2\u003eCrossovers Between Paired Cylinders\u003c\/h2\u003e\u003cp\u003eThe header carries 1-2 and 3-4 crossovers: short balance pipes linking the cylinders that fire together on an inline four.\u003c\/p\u003e\u003cp\u003eTheir job is to let the pressure pulse from one cylinder help scavenge its partner, which fills in the parts of the torque curve a straight four-into-one leaves hollow. It is a detail you cannot see once the fairing is back on, and it is one of the reasons a full system behaves differently from a slip-on rather than just sounding different.\u003c\/p\u003e\u003ch2\u003eWhat Goes Behind It\u003c\/h2\u003e\u003cp\u003eSpark sells the Evo 2025 range in sections so the header and the back half can be chosen separately. Behind this one goes either the plain titanium link pipe SGHO8847*01 or the pre-silenced SGHO8849*01, and then a silencer group.\u003c\/p\u003e\u003cp\u003eIf you already know you want the link pipe, GHO8847R is the same header supplied with it, and the two routes come to within about ten euros of each other. Buy this number if the link pipe decision is still open, or if you are replacing a damaged header on a bike that already has one.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eHonda CBR 1000 RR-R, 2024 through 2026.
