Proportionally, nothing in the four-figure part of this range comes close.\u003c\/p\u003e\n\u003ch2\u003eNo Remap Needed\u003c\/h2\u003e\n\u003cp\u003eAkrapovic states the installation is plug and play and that no remapping is required. Combined with the lambda thread, that means two things at once: the bike runs correctly straight away, and it remains tunable later if you want more.\u003c\/p\u003e\n\u003cp\u003eMost headers force the choice. This one does not.\u003c\/p\u003e\n\u003ch2\u003eBuilt for the Titanium Slip-On\u003c\/h2\u003e\n\u003cp\u003eThe header is designed to increase the tuning potential of the Akrapovic Slip-On Line (Titanium) for this machine — S-H3SO11-BNTA. Fitted together, the two form a complete exhaust from the cylinder head back, and the sound is deeper and sportier than the slip-on alone gives.\u003c\/p\u003e\n\u003ch2\u003eA Quarter of a Kilogram\u003c\/h2\u003e\n\u003cp\u003eThe header itself weighs 0.6 kg against 0.85 kg standard. In absolute terms that is nothing, and this page is not going to claim otherwise — the weight is a side effect. The reason to buy it is the tuning headroom and the six per cent power gain.\u003c\/p\u003e\n\u003ch2\u003eWhat Removing the Catalytic Converter Means\u003c\/h2\u003e\n\u003cp\u003eThe standard CRF300L header contains a catalytic converter. This one does not, which is where the power comes from and also why there is no road approval. There is no version that does one without the other.\u003c\/p\u003e\n\u003ch2\u003eForty Minutes\u003c\/h2\u003e\n\u003cp\u003eThe CRF300L's single cylinder puts its exhaust port in the open, and there is no fairing in the way. Forty minutes covers the header on a bike on a stand, with no special tools needed.\u003c\/p\u003e\n\u003ch2\u003eThe Cheapest Route to a Full System\u003c\/h2\u003e\n\u003cp\u003eIf the Slip-On Line is already fitted, this header turns it into a complete exhaust for a fraction of what a Racing Line costs. That combination is the least expensive full system for any motorcycle in this catalogue.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eE-H3SO1 covers the Honda CRF300L from model year 2021 through 2026.
