The sections that take impacts from roost and from the bike going down are thicker; the sections that only carry gas are thinner. That is why a system this light survives a motocross season.\u003c\/p\u003e\n\u003cp\u003eIt is also the reason this is the flagship line. A cheaper system uses one thickness and compromises in both directions.\u003c\/p\u003e\n\u003ch2\u003eFIM Noise Limits\u003c\/h2\u003e\n\u003cp\u003eCompetition noise rules are the constraint that shapes a modern motocross exhaust, and Akrapovic addresses them through the muffler's profiled surface rather than through added packing. The muffler is also the largest the frame will accept, which gives more volume to silence with.\u003c\/p\u003e\n\u003cp\u003eThe practical effect is that this system will pass scrutineering at an FIM-regulated event. A louder system would not.\u003c\/p\u003e\n\u003ch2\u003eThirty Minutes\u003c\/h2\u003e\n\u003cp\u003eA motocross exhaust has to come off for cleaning and go back on between motos, and Akrapovic designed for that. Half an hour covers the whole system — headers and muffler both.\u003c\/p\u003e\n\u003ch2\u003eThe 450 Is Where the Power Gain Lives\u003c\/h2\u003e\n\u003cp\u003eCompare this system with the same line for the CRF250R and the difference is stark: 2.8 PS here against 0.7 PS there, and 26.5 per cent weight saved against six per cent. A 450 motocross engine simply has more to give.\u003c\/p\u003e\n\u003cp\u003eThat is not a criticism of the 250 system, which is doing a different job. It is the reason the 450 version is the easier purchase to justify.\u003c\/p\u003e\n\u003ch2\u003eNot the 2025 Bike\u003c\/h2\u003e\n\u003cp\u003eHonda revised the CRF450R for 2025 with a new frame and a changed exhaust route. This system covers 2021 to 2024 and does not carry over.\u003c\/p\u003e\n\u003ch2\u003eAlso for the RX\u003c\/h2\u003e\n\u003cp\u003eHonda's CRF450RX is the cross-country version of the same machine, with a larger tank, a kickstand and different suspension settings. It shares the exhaust route, so this system fits both.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eS-H4MET16-FDHLTA covers the Honda CRF450R and CRF450RX from model year 2021 through 2024.
