SERIE PRO - DSE Racing Exhaust for PX200 and Largeframe - High-end system for powerful setups. From DIRTY SOUTH ENGINEERING, manufactured by JIM LOMAS.
The SERIES PRO range bundles selected performance parts from small tuning forges - the DSE Exhaust is one of the most uncompromising systems for 200cc Engines with over 25 hp.
- Extremely powerful - proven on the quartermile
- Handmade by JIM LOMAS in a limited series
- For 200cc high-end setups and 177cc racing applications
"DSE - DIRTY SOUTH ENGINEERING" developed the Exhaust in cooperation with SESC for heavily modified PX200 Engines. As early as 2006, the system impressed with victories in the quarter mile, including in Bremen at 157 km/h. A 221 cc MALOSSI setup achieved over 41 hp at the rear wheel. The prerequisites are appropriately machined engines with long timing (approx. 130°/190° to 130°/195°), a large intake and powerful peripherals.
The system is made of steel or stainless steel, hand-welded from many segments and supplied with stainless steel silencers depending on the version. Lefthand design, fastening via Springs on the Exhaust Manifold. Wide tire mounting is possible, spare wheel and Centre Stand are not required. Jetting and Ignition must be adapted.
A version for smaller PX models and older largeframes has also recently become available - ideal for high-bred 177cc setups.
Conclusion: The SERIE PRO - DSE is an uncompromising powerhouse with genuine racing DNA and high quarter-mile competence.
SIP-TIP:
- Large Intake Manifold (e.g. MBD/MMW) and at least 32 mm, better 35 mm Carburettor are mandatory. Reinforced COSA Clutch or MMW basket required. Reed Valve or Flowed Crankshaft, reinforced gearbox and CDI Ignition are advisable.
Feedback
"The 'how' is known and proven, and if you don't have two left hands, you get a fully road and touring capable Engine with 30+ hp at the rear wheel."

Note: JL EXHAUSTS has been facing significantly higher material and labor costs for some time now. In addition, tariffs, bureaucratic requirements, and a shortage of skilled workers are driving up production costs. As a result, prices have been adjusted effective 07/2025. For the most popular racing exhaust systems, we were able to partially offset the elevation; however, certain models will be permanently discontinued.
The exhaust systems continue to be handcrafted in Europe. Low noise levels, high durability, clean welds, and high-quality materials such as stainless steel continue to characterize these systems.
