The Superbanana from EGIG PERFORMACE is a resonance exhaust, based on the look of a conventional banana exhaust, as already used by Piaggio ex works on the popular SS50/90 and ET3 models. The Superbanana is designed to provide powerful engines from 125cc upwards with an exhaust that is visually and acoustically unobtrusive, but operates at the level of a classic resonance exhaust.
SOUND INSULATION
There is a silencer inside that reduces the volume to the lowest possible level without causing any loss of performance or heat build-up. The difference in noise development compared to an original or other classic 'bananas' is only a few DB more and that with +50 % or more power increase, depending on the engine type.
FEATURES SUPER BANANA TOURING
One-piece exhaust
Overflow angle: 120°-125°
Exhaust angle: 170°-180°
Pre-exhaust angle: 27-29°
Manifold Ø32mm
Luggage compartment compatible
Tires up to 3.50 width
Stud bolt distance 54-62 mm*
Not suitable for Vespa PK (can also be fitted to PK models by cutting out the side plate)
*If the Superbanana is installed at 54 mm, the M8 collar nut with 10 mm wrench size supplied with the exhaust must be used on the inside of the manifold.
The Superbanana exhaust systems are designed as the final expansion stage for fast road engines. They therefore need the right environment to deliver the appropriate performance. If the engine is still standard (or has been built rather conservatively despite the 133cc cylinder), the exhaust can only provide limited support. In this case, we would rather recommend a BGM Touring or BGM Sport Banana, as these can support the engine much better in such an environment. However, if the conditions are right (cylinder, intake revision, carburetor size, etc.), the Superbanana currently offers the highest increase in performance that can be achieved with an inconspicuous exhaust system.
In order to meet different requirements, there are two different types, the Sport and Touring versions.
TOURING
The Touring version is a 'real banana' in terms of its characteristics and scores points for its good rideability thanks to the high torque that is available relatively early on. In the upper rev range, however, it still has plenty of reserves to complete fast stages on the highway.
Depending on the cylinder and exhaust angle, the power peak is between 7000 and 8000 rpm and thus approx. 1500 rpm later than with a conventional sports banana. It therefore feels at home on engines with not too high control angles (overflow max. 125°, exhaust ~170-180°, advance angle between 27 and 29°) and is perfect for touring engines based on a Polini 133 or an M1B 60, for example. The Touring is comparable with Egig Python or PM40, for example.
SPORT
The Superbanana Sport has a larger diffuser and was developed for high-performance engine concepts. For optimum results, it is therefore also used with higher control angles than the Touring. The overflow angle should be around 126-128°, the advance angle between 29 and 32°, resulting in a window for the exhaust angle of approx. 184-192°. Depending on the set-up, the Sport then produces real fireworks and peaks between 8000 and 9000 rpm with a good usable overrev of usually over 2000 rpm.
You should therefore not be too confused by the design, the Superbanana Sport is a 'whole guy' and plays in the same league as the Egig Mamba or Viper resonance exhaust.
The manifolds of the Superbanana Sport and Touring are identical, so it can be converted in just a few minutes if necessary. The exhaust should be oiled regularly to protect it from rust. Alternatively, it can also be painted with heat-resistant paint or electroplated.
NOTE: The exhaust manifold can touch the shock absorber spring. To ensure sufficient clearance, we recommend using the 'Joe Possum' shock absorber adapter from CMD (see accessories).
CONCLUSION
The EGIG PERFORMANCE SUPERBANANA exhaust systems are perfect for inconspicuous but powerful smallframe engines. They score points with high performance, good drivability and a wide rev range.
