An HGS exhaust header for the KTM 450 EXC-F from 2017 to 2019.

HGS has been building exhausts for motocross tracks and off-road use since 1988. The brand was founded by Henri Gorthuis, who worked as a mechanic in Grand Prix in the 1980s, and is now in the hands of the third generation. The exhausts are made in the Netherlands and are used worldwide by racing teams.

For a two-stroke engine, the header determines the engine's character. HGS tunes the shape and volume to the engine block, focusing on controllable pulling power rather than an abrupt power peak.

• Direct replacement, no modifications needed

A motocross exhaust is racing material and is not permitted for use on public roads. Have it installed by someone who knows what they're doing, regularly check the gaskets and springs, and re-tighten bolts after the first ride.
