Standard looking racing exhaust, the evolution of the oft copied original. The MK 3.0 version of our subtle SIP ROAD EXHAUST yet again pushes the envelope of performance. Unlike the competition we have crammed all this performance into the compact body of the original box.

TUNING ROAD - for everyday use

For race use only. Not admitted in the area of the German StVZO!

The SIP ROAD was and is the benchmark for all box pipes. It introduced the concept of a racing pipe that keeps the box look of the original Piaggio Largeframe item to a wider public. And it made it as popular as it rightly is today. Among its most attractive features are the excellent rideability, and easy tuneability, particularly on engines that already run the SIP ROAD 2.0. In recent years many have tried their hand at an exhaust inspired by the original, quite a few have actually launched their version. Engines with this concept have reached impressive levels of power and torque, and some even beat the godfather, our SIP Road 2.0 box in terms of outright performance. The ease of use, and the launch torque are yet to be improved upon though.

  • Original Look with original sized box
  • Massive torque, just perfect for a daily rider
  • Excellent for plug and play tuning with original carburettor

Still the time had come to go one better and develop a new box. The benchmark was there, and the requirements were defined: It should still work on any type of engine. It should operate at low and real-world usable rpm, it should beat the best in that range, and it should still keep the original dimensions of the box. The new SIP Road 3.0 should remain subtle and compact. The last in particular turned out to be a real challenge. Others use larger boxes to find performance, which, of course, makes life much easier. Unfortunately squaring the circle takes time, so development took a little while. The result is worth the wait though. A small box that works well with a vast variety of engine setups while keeping up with the very best in terms of performance.

Accessible performance in whatever situation

Comes into the powerband early to make the ride to work as enjoyable as the tackling of an uphill alpine pass. Our reference for the development where kits such as the Malossi Sport or the Polini. But Quattrini or Pinasco kits work extremely well with the SIP Road 3.0. It’s great combined with an SI carburettor, little effort to fit with proven reliability.

Modern manufacturing and design

To get to the level of performance of the SIP Road 3.0 not only development took its time. Manufacturing too is a bit more demanding. The downpipe is not made of segments. It’s a cold drawn design with an upper and a lower halve. This helps with minimising the tolerances between individual pipes, and there are less welding-seams perpendicular to the gas flow direction. Apart from that this technique also made it possible to route the downpipe in tighter curves without any negative effects. This had become necessary to make sure the larger downpipe did not conflict with other parts, such as the main stand.

New quality with proven advantages

Significantly more torque and massively higher power. With a Malossi Sport on a P-Range the difference in power over the SIP Road 2.0 may be anything up to two BHP. This is also the case with the classic setup for the small blocks. A 177 Polini also recorded an increase of approx. 2 HP with the Road 3.0 compared to its predecessor. This promises a relaxed ride with no problems when shifting up at all. The sound of the SIP ROAD is nicely understated without drawing unwanted attention, that makes it ideal for cities and for the daily ride. Please do not forget to adjust the jetting and the ignition.

Conclusion: the SIP ROAD 3.0 is an excellent update of an exhaust classic. All the great features of the MK 2.0, the fit, the quality and precision of manufacturing, are retained while the power goes up slightly by about 2 BHP. A racing pipe that looks like the original box exhaust. More torque and more power, heat resistant paint, excellent value for money.

Technical details:

  • Significantly more power and torque than the SIP Road 2.0, +10-25%
  • Based on the original sized box
  • Drawn downpipe for a precision built and more power
  • Excellent fit for an easy plug-and-play mounting
  • Tight downpipe routing for maximum lean angles
  • Uses additional springs to take stress of the exhaust stub

The chrome version may have a slightly less precise fit due to the manufacturing process. They can still be mounted. It is best to first place the screw in the crossbar and loosely screw it into the thread of the locknut. Then pull the exhaust over the outlet. This requires a little force, but makes the assembly easier.
