The SIP Road 3.0 racing exhaust has been a classic and perennial favourite in our range for years. Now the racing exhaust 3.1 from SIP Performance follows. We have made some improvements and raised the SIP Road racing exhaust to a new level.
We remember: At the time, we developed the SIP Road 3.0 to be inconspicuous and compact. This proved to be the biggest challenge. Many manufacturers use larger boxes because it is easier to gain performance with a larger volume. The result was impressive: A small box that can be combined well with a wide variety of setups and has no need to shy away from any comparison in the field of touring boxes.
What's new with the SIP Road 3.1 race exhaust
The racing exhaust has connections for EGT and AF, so you can use our exhaust gas temperature gauge and lambda probe with the SIP speedometer/tachometer. We have also fitted a new manifold flange. It seals with an O-ring and can also be screwed on. This means that the exhaust is not only 100% tight, it also does not cause any vibrations. To make the connection perfect, the exhaust can also be secured with springs. On the 3.1 version, these are encased in rubber to prevent "whirring".
Comfortable power delivery in every riding situation
The performance of the SIP Road 3.1 is absolutely identical to that of the 3.0.It comes on early and unfolds in a range that makes the way to work relaxed and the pass uphill confident. The reference for the development were cylinders like the Malossi Sport or the Polini. But also a Quattrini or Pinasco racing cylinder runs excellently with the SIP Road 3.1. Combined with an SI carburettor for low conversion effort and reliable mechanics.
Modern in manufacture and design
In order to achieve the extra performance compared to the SIP Road 2.0, not only did a lot of time have to be invested in the development, but the production also requires a little more effort. The manifold is not made of individual segments, it consists of pressed upper and lower shells. This minimises tolerances between the individual exhaust systems and there are fewer weld seams that are perpendicular to the flow direction of the exhaust gas. In addition, we were able to realise a tighter radius without any losses. This was necessary to accommodate the larger manifold in such a way that neither cornering clearance was restricted nor did the exhaust come into contact with other components such as the kickstand.
Qualities with proven advantages
Significantly more torque and a full increase in power. On the PX200 with Malossi Sport, depending on the setup, it's 2 hp plus on the SIP Road 2.0. It's the same with the classic setup for the small blocks. A 177 Polini also registers an increase of approx. 2 hp with the Road 3.1 compared to its predecessor. This promises riding comfort and ideal gear shifting. The sound of the SIP ROAD is pleasantly discreet and not too obtrusive, ideal for the city and everyday cruiser.
When fitting, please always make sure to adjust the fuel injection and ignition timing.
If Vespa 125 VNA-TS/150 VBA-T4 pilots remove the 2nd tab of the exhaust, they can also ride all SIP Road PX models.
Conclusion: The SIP Road 3.1 racing exhaust is an update with useful additions to the tried and tested 3.0 version.
