An HGS exhaust header for Husqvarna, KTM from 2025 to 2026.

HGS has been building exhausts for the motocross track and the woods since 1988. The brand was founded by Henri Gorthuis, who worked as a mechanic in Grand Prix racing 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 character of the engine. HGS tunes the shape and volume to the engine block, focusing on manageable traction rather than an abrupt power peak.

• Made in the Netherlands
• Direct replacement, no modifications needed
• Developed and tested with racing teams
