Our first products were for the popular racing Yamaha TZ250 and TZ350, following success in racing many of the British racing teams used our exhausts including:
Padgetts of Batley, Zip Karts, Steve Webster Racing etc……

In 1988 we started production of exhausts for Superkart racing, in our first season we achived 1st and 2nd positions in the British 250cc Superkart championships. From 1989 – 92 our products won every major Superkart championship in the world including:
British, Swedish, South African, Australian, European and World.
At one race at LeMans in France of the sixtysix karts, fortyfive of them were equipped with JL exhausts.

Since we made our first TZ250 exhausts 27 years ago we have made high performance exhausts for a variety of applications:
Road Racing Motorcycles, Motocross, Quads, Karts, Sidecar Racing, F500 Car Racing, Scooters and Jet Ski.

Perhaps our best known product are for the Yamaha RD350LC and YPVS350, they have been in continuous now for 23 years. These popular exhausts were derived from our race winning F2 world championship bikes and were also winners of the Isle of Man TT races.

Our most famous customer 10 times Sidecar World Champion used our exhausts in the early 1980’s to win the British Championship, breaking ever circuit lap record in the process.

Nowadays we are also known for our extensive range of scooter exhausts especially for the classic Vespa and Lambretta models, following a request from our German distributors we pioneered the production of stainless steel exhausts for high performance 2-stroke exhausts.

In 1993 Jim Lomas moved the exhaust production to the Czech Republic with his wife Helenka and son Oliver where we continue the ongoing development of our unique Jim Lomas designed exhaust products.

New products for 4-stroke motorcycles and scooters are in the final stages of design and
development for 2007.
