Product information "Side-pipe exhaust system"

Classicbike-Raisch x Mass Side Pipe Exhaust System for Triumph Bobber Euro 4 / Euro 5 (up to 2024)
2-2 stainless steel complete system in Hot Rod design – with E-mark / road approval

In our opinion, side pipes are the best-looking exhausts for a Bobber.
The system is nice and short, which keeps the rear of the motorbike uncluttered. What’s more, the significantly thicker manifolds compared to the originals, along with the short, beefy rear silencers, ensure that the Bobber looks and sounds truly powerful.

The Side Pipe is a complete exhaust system; the original catalytic converter is retained. And, as an added bonus, it’s also 4.8 kg lighter than the Bobber’s original exhaust.

Sound

The sound is nice and rich & deep.

With the Side Pipe, you have 6 sound options to choose from:
- Standard configuration with the fitted DB killers (which can be removed with a single screw).
- With racing DB killers, which make the motorbike louder but still have DB killers fitted (these must be ordered separately; see the accessories section in this description).
- Without DB killers
- With the catalytic converter flap removed: a plate is welded (temporarily attached) between the manifolds, ensuring that the exhaust gases pass through the catalytic converter. You can cut this plate out, which directs the exhaust gases straight through the manifolds. In other words, this gives you a straight pipe and effectively bypasses the catalytic converter. You can then use this option with any of the three different DB-killer variants.
You can also see the plate in the product photos.

Materials & Manufacture

With our first in-house exhaust system, it was particularly important to us that it not only had an attractive design but was also of a very high quality.
The side pipe is handcrafted in Italy by Mass, a company with whom we work very closely. The manifold pipes are significantly thicker than the originals and therefore look much more substantial.
The workmanship, the material and finish, as well as the precision of the fit, are all excellent.

Fitting

We recommend ordering a set of manifold gaskets along with the exhaust system (see accessories listed in this description).

Do you have a Bobber Euro 5+ (from 2025)?

No problem – we also have an exhaust system in our range for this. It comes with a new catalytic converter and is therefore type-approved / legal.

Not bothered about legality? Then, to save money, you can also fit this exhaust here and install a second-hand catalytic converter from a Euro 4/5 Bobber or an X-pipe.

Power Kit Stage 5 - Bobber +29 hp CB12745 / RS0

PowerKit Bobber 1200 / Speedmaster 1200 Stage 5 consists of: Airbox Eliminator Kit USB stick with RAISCH special mapping for direct transfer to the ECU ATTENTION: With the Stage 5 kit, it is essential to use our side pipe exhaust system (completely open). If you have not yet installed the exhaust system, you can order it separately (you will find the exhaust system under the accessories in this product description). Peak power + 27 hp. Peak torque + 13 NMVmax speed limit of 179 km/h is removedMaximum RPM increase + 800 rpm At approx. 6800 rpm, you can even achieve an increase of 29 hp and 30 NM At approx. 4500 rpm, you can already achieve an increase of 8 hp and 12 NM. Now there's real pressure in the boiler! Looking at the performance curves, you would think that two different motorcycles were measured here. The difference or gain is incredible! The entire rev range becomes enormously more powerful. The engine revs more willingly, feels simply freer and livelier, can now breathe in freely and exhale with maximum freedom! From the mid-range onwards, it really takes off, and in the upper rev range, where the engine feels very tired with the standard setup and it's hardly worth revving higher, it now burns like fireworks. The side pipe exhaust system fits the Bobber perfectly and teases out the engine's full potential. The power feels like it never wants to end. The throttle response is nice and smooth and load change reactions are significantly reduced, which noticeably improves rideability. The intake sound through the single air filters is simply brilliant, but not too pronounced! The exhaust sound with the open side pipe exhaust system is really powerful. The increase in performance and improved rideability are active in all riding modes. The driving modes with their respective characteristics can of course still be switched and used. The figures in the diagrams are rear wheel measurements, see general description in the product group. Our mappings were determined on the test bench with a great deal of time and effort. These mappings can be transferred to the vehicle yourself using the app + Bluetooth OBD adapter (see below for more information), resulting in a plug-and-play solution. This saves you having to have your bike tuned on a test bench, which can be very expensive. In addition to the increase in performance, the engine also runs more smoothly and quietly overall. We increase the rev limit by 800 rpm, which is well within the healthy range. This kit is not road legal and is only intended for use on non-public roads. Installation is relatively easy to do yourself. When ordering, please enter the complete chassis number in the comments field during the ordering process! Installation and mapping can be carried out at our premises by appointment for an additional charge. Info: If you would like to get an overview of the requirements and how to program the ECU beforehand, please click on the file ‘Information on ECU tuning’ under Downloads (below the product description). You will find a suitable Bluetooth OBD adapter under Accessories below this description. Additional information: If you do not feel confident programming the ECU yourself or cannot travel to us, please contact us for alternative solutions with an additional tuning box (Power Commander). Optional accessories: Filter care/cleaning & blackening:When new, the DNA filters are purple due to the oil with which they are lubricated. If you don't like this, you can blacken the filters with the appropriate K&N oil.For maintenance/cleaning of the filters, we recommend ordering the air filter maintenance kit (see accessories in this description). After cleaning and oiling, the filters are slightly purple again (as a tip for those who like purple). Side cover retaining kit:If you would like the Airbox Eli Kit to be a little less conspicuous, or if you simply want to keep the original side covers, we offer a retaining kit that allows you to reinstall the original side covers, even without the airbox. This gives you a clear view of the air filter area from the rear, while still enjoying the extra power. You will find the accessories under the product description.
