Built by a Brand with Deep Racing Roots
HGS Exhaust Systems was founded in 1988 by Henri Gorthuis, a former Grand Prix mechanic who worked with top-level teams and legendary riders such as John van der Berk. Drawing on decades of motorsport experience, Henri built HGS into a brand synonymous with innovation, performance, and uncompromising quality.
With a family legacy in exhaust building—Henri’s father crafted performance systems for BSA motorcycles in the 1960s and '70s—HGS represents three generations of engineering expertise. Today, Henri’s son William carries on the family tradition as part of the next generation of HGS engineers.
A Track Record of Success
Since 1995, TM Motorcycles has chosen HGS as its OEM exhaust supplier.
In 1997, legendary manager Jan De Groot selected HGS for his De Groot Racing team—where it’s still used today.
HGS played a key role in Stephen Sword’s 2004 British MX2 Championship win.
HGS systems are used by elite GP-level teams and top-level privateers worldwide.
This stainless steel header pipe is part of that same racing pedigree—designed not just for fitment, but for podium-topping results.
