HGS: motocross and enduro exhausts with a racing history

HGS Exhaust Systems was founded in 1988 by Henri Gorthuis, following his experience as a mechanic in motocross Grands Prix during the eighties. Exhaust manufacturing was already part of his family background: his father had built systems for BSA off-road motorcycles in earlier decades. This specialisation led to a company in the Netherlands dedicated to exhaust systems for two-stroke and four-stroke engines.

Based in Oss, HGS connects its product development with Dutch sand tracks and work in racing. Its family story continues with a third generation involved in the company. At Motarea, you can explore both the main components and the spares needed to maintain an HGS exhaust, distinguishing each part’s function and its specific application.

HGS silencers and 2T expansion pipes

The HGS silencers include references for 2T and 4T engines, with different bodies, inlet pipes and end caps. The catalogue includes versions with stainless steel or carbon fibre end caps. The outer material and shape help you compare options, but your choice must match the engine, mounting points and exhaust system on which the silencer will be installed.

The HGS expansion pipes for 2T engines form another of the brand’s main product families. Their expansion chamber and geometry distinguish them from a four-stroke header. You will find Factory references and variants that the catalogue identifies for particular configurations. Always check the exact application and the parts that the expansion pipe needs to work with.

Headers, link pipes and complete exhaust systems

The HGS headers for 4T engines include stainless steel parts with specific shapes and mounting points. The exhaust link pipes serve a different function within the assembly: they connect its sections according to the design of each reference. Check the joints, brackets and compatible exhaust components; two pipes that look similar are not necessarily interchangeable.

You can also browse complete HGS exhaust systems when considering an assembly rather than a separate part. The contents listed on the product page let you distinguish the components supplied from those that must be retained or purchased separately.

End caps and repacking kits for maintenance

The HGS silencer end caps let you find replacement end pieces in carbon fibre or stainless steel. Choose them by shape, diameter, mounting method and the silencer they are intended for. The HGS repacking kits complete the maintenance range with separate references for 2T and 4T silencers; check the size, application and contents of each kit.

Browsing these families helps you prepare a replacement or repair with the corresponding parts. Before buying, check the reference, documented compatibility and installation and use conditions for each HGS product.
