A little update necessary? The SITO Plus is the ultimate alternative to the original PIAGGIO item and also the first step into the wonderful world of performance exhaust systems. Hardly distinguishable from the original, the SITO Plus impresses with its inner values. It provides a noticeable power increase in the mid and upper rev ranges and so guarantees an improved performance especially with standard cylinder setups, more constant acceleration is also made possible while changing up from third to fourth gear.
Based on the original PIAGGIO T5 exhaust design, this pipe not only has a very high build quality and the exact fitting dimensions, but also the freedom offered by the original to fit a wider section tyre, more cornering clearance and the obvious advantage of still being able to carry a spare wheel. The SITO Plus exhaust system is available universally for all VESPA motors in the PX range including all tuning cylinder setups, from the humble DR 135cc to the mighty MALOSSI “CVF” 210cc cylinder: Perfect for touring motors, more performance and with a more sporty tone included in the price. Original T5 motor exhaust systems are no longer available. Long live the SITO Plus...
The SITO Plus is BSAU approved and safe for use in the United Kingdom. If you need to register the scooter in Germany for any reason then you will have to have a chat with the local TÜV vehicle inspector beforehand.
Conclusion: The SITO Plus exhaust system is THE ideal all-rounder with a discreet appearance and a wide power delivery. A performance orientated completion of original motor setups and the cherry on the cake for tuned touring setups and that for very little money.
Racing exhaust system/ Steel construction/ painted black/ includes BSAU No.
Steel, black painted, exactly to fit from high quality steel, near original SITO Plus sound.
This exhaust pipe allows the use of larger tyre sizes, a spare wheel and also the main stand.
Carburettor jetting and ignition timing should be checked and/or altered.
SIP-TIP: A larger main jet and adjusted ignition timing are absolutely necessary for optimal and reliable use of this exhaust system. We recommend also a long stroke crank and a 24/26 mm carburettor, a touring flywheel and an after market ignition (Parmakit or Vespatronic), a DRT gearbox and a COSA clutch complete the ideal touring setup.
SIP community user “Nase”: “First of all I tried a Taffspeed MK4 and then the SIP Performance race expansion chambers with an original PIAGGIO cylinder setup. The rev-range was higher with the expensive pipes but the SITO Plus definitely had more usable power on offer!”
PX 80-125 Exhaust Test, Scootering (July 2013): “The Sito+ concept is standard looks plus a little bit more performance. This box pipe based on the original T5 exhaust layout has always worked well. Despite being slightly louder and tinnier than the stock Sito it carries a BSAU 192T3 approval stamp, which is important for some markets. The Sito+ delivers a useful performance boost across the rev range, but it is no longer the best performing box pipe.“
