Optional Header (SS) for HONDA MSX125 / GROM 2025

Offering an impressive increase in power of over 10% and a huge weight savings of 48% over the stock item, the header provides increased tuning potential when used with the Slip-On Line (Titanium) exhaust. It is constructed using high-grade stainless steel, has a thread for the lambda sensor for those planning to tune the engine electronics, and has no catalytic converter. Power is increased by 13.6% at 8,600 rpm, with torque increased by 14.7% at 8,700 rpm when tested on the Akrapovič dyno against a Honda MSX 125 with a standard stock exhaust. This adds a distinctive deep and sporty sound. It features easy plug-and-play installation, and no remapping is required. This exhaust is meant for racetrack and closed course use only.

This product does not fit on motorcycles equipped with 2 lambda sensors.
