Welcome to JL exhausts by Jim Lomas

Jim Lomas started exhaust manufacture in 1979 at Wymondam, Norfolk, Great Britain.

Our first products were for racing Yamaha TZ250 and TZ350. In the early 80s, many top British racing teams used JL products including Padgetts, Zip Karts and Steve Webster.

In 1988, we had our first season supplying exhausts for Superkart racing; in this first season we achieved 1st and 2nd places in the British 250 Superkart Championships. From 1989 to 1992, our exhausts were used to win every major Superkart 250 Championship around the world including Great Britain, Sweden, South Africa, Australia, Europe and World Championships.
