Akrapovic Stainless Steel Header Pipe Honda CRF 300 (L / Rally) 2025-26

Upgrade your Honda CRF300L / Rally with the Akrapovic Stainless Steel Header Pipe

Designed for riders seeking maximum performance, sound, and tuning potential. This optional header is engineered to pair perfectly with the Akrapovic Slip-On Line (Titanium), creating a race-focused exhaust system with enhanced power and responsiveness.

Constructed from premium stainless steel, the header features a pre-fitted thread for the lambda sensor, ideal for riders planning to fine-tune engine electronics. With no catalytic converter, it delivers unrestricted flow and a deeper, more aggressive exhaust tone.

Dyno-tested against the stock Honda CRF300L exhaust, the header provides a +1.5 bhp increase at 7,650 rpm while producing a richer sound. Noise is measured at 90.4 dB at 4,250 rpm, an increase of 2.6 dB over the standard system, with a far sportier and deeper tone.
