Performance it does exactly what it says on the label. It has been the most popular large frame tuning exhaust system for the last 10 years. Jim Lomas, himself active as a racer in the 60s, began in 1979 to produce performance orientated expansion chamber exhaust systems for two stroke motors. Due to the enormous demand from the scooter scene revival of the day, he soon decided to concentrate his efforts to the enhancement of the VESPA and LAMBRETTA scooter ranges. The later emerging German and Austrian street racer scene were in need of a pipe that could be used for maximum power and rev range setups, with an especially voluminous expansion chamber for low to mid range torque delivery. In 1997 we combined our strengths with Jim’s and developed the Performance expansion chamber system: loads of oomph from way down the rev range, stainless steel construction, allows the use of a main stand and wide tyres. Over the years this system has been constantly improved and updated and sadly (badly) copied.
This exhaust system is hand finished in stainless steel. It is also available with a polished finish. A double walled construction in vital places ensures less noise output, increased solidity and an eye catching rust free design. It is mounted to the motors exhaust stub manifold using springs. The main exhaust mounting bracket is robust enough for the stress and strain of normal daily use. We decided against the use of O-ring exhaust gaskets to enable sufficient flexibility and so reduce danger of the pipe being cracked or otherwise damaged. This exhaust system can be used in combination with original PIAGGIO cylinders and virtually all states of tuned motor setups, from mildly tuned road going scooters through to maximum power projects. A broad power potential can be realised from 15 PS through to 28 PS, enabling potential top speeds of between 105 and 150 km/h (62
90 mph!).
The other exhaust in this range, the EVO Racing exhaust is almost identical to the Performance exhaust in construction, differing only in that the EVO is constructed using normal (non stainless) steel and powder coated. There are two versions of this pipe available for the VESPA T5 models. The unit including the shorter downpipe manifold is suited to the more higher revving motor setups. It is especially harmonious in combination with the original PIAGGIO 125cc cylinder. The Performance NT represents the version with the longer downpipe manifold section. This unit ensures power delivery in the lower and mid rev ranges and so lends itself ideally to MALOSSI or POLINI cylinder setups.
JL Guarantee:
Included with every-Performance expansion chamber system is an automatic 3-years warranty from date of purchase for all original purchasers, if your exhaust splits open at any time during normal use (apart from grinding it along the curb) it will be repaired or replaced.
Conclusion
: A completely convincing sound and performance. The Performance expansion chamber system is suited for the more milder road going scooters and also maximum power tuning projects.

These exhausts allow the continued use of both the main-stand and wider section tyres are also possible.
Carburettor jetting and ignition timing should be checked and/or adjusted for reliable and enduring use of this exhaust system.
