JL RST Racing Exhaust (Bolt-On) – Race Super Tour
Material: Black steel, without rear silencer

The JL RST (Race Super Tour) is one of the most powerful and versatile resonator exhausts for Lambretta Series 1–3. Developed by Jim Lomas / JL Exhausts and optimized on the test bench, it delivers noticeably more power and torque in the low- to mid-rpm range than the classic KRP3 and maintains engine speed longer. 

Advantages & Features

• More power and torque in the low-to-mid range with longer-lasting power delivery
• An excellent all-around choice for high-performance touring engines 
• Very similar to the Franspeed Super Tourer
• Nylon/plastic bushing bearings (suspended mounting) → less wear and a significantly lower risk of cracks
• Reinforced mounts + 3-point mount on the rear shock
• New slip-joint design at the connections (better, more durable)
• Bolt-on flange plate → standard 3-hole rear mufflers are easily replaceable
• Powder-coated steel body (black)

Ideal for touring engines that need to be powerful and high-torque, but also for ambitious tuned engines. Similar RPM range to the KRP3, but more powerful and with a broader power band.
