1/41
3rd place: Hattech Dark Style
The Hattech muffler not only gives the GS a powerful sound, but also scores with a high-quality appearance.
BILLION
2/41
The laser remains weak in terms of sound and performance.
Lohse
3/41
Workmanship, fit and noise development are pleasing to the beautifully made BOS GP-2.
BILLION
4/41
Only on the test bench does it stay lean.
Lohse
5/41
The original damper therefore occupies eighth place. From the factory, the boxer scores with a cleanly processed silencer that allows dirt to accumulate quickly. Pleasant sound.
BILLION
6/41
The performance of the original damper from the BMW factory.
Lohse
7/41
7th place: SC Project SC-1
What a sound! The word silencer seems a bit out of place at SC-Project.
BILLION
8/41
The finish is great, but whether the race management agrees mildly?
Lohse
9/41
6th place: AC Schnitzer Stealth
Slim shaped bag with a very attractive finish. The exhaust of the BMW tuner goes well with the GS and sounds good.
BILLION
10/41
No plus in performance.
Lohse
11/41
5th place: Termignoni slip-on
The one-piece system scores with its excellent surface quality and wraps the boxer in a fat cloud of sound.
BILLION
12/41
Deficit: the performance.
Lohse
13/41
4th place: Zard Slip / on
The bag, which tapers to a point at the bottom, suits the GS exceptionally well and gives it a rich bass tone.
BILLION
14/41
No plus in terms of performance.
Lohse
15/41
The Laser Hotcam Dual Sound scores with its technically good appearance with a solid fit on the GS.
BILLION
16/41
Unfortunately, the performance remains below the series.
Lohse
17/41
Shark, Laser and BOS share the next places. The Shark Competition DSX-5 is an inexpensive rear silencer that looks good with the GS. The sound is too shrill for the boxer.
Ems
18/41
MOTORRAD took a closer look at a total of 14 models.
Frill
19/41
The connecting pipes of all silencers fit the standard manifold of the GS. Only with Hurric and Shark cannot the heat plate be mounted.
Frill
20/41
Beautifully made details such as a heat plate specially made in the BMW GS look (Termignoni) are unfortunately only available from a few suppliers.
Frill
21/41
Sharp-edged protrusions such as the screw that is too long for the clamp on the connecting pipe of the Arrow exhaust can cause injuries when cleaning.
Frill
22/41
Since the mufflers should fit on many motorcycles, it can get very tight depending on the model type – as here with the indicator in the exhaust flow of the Arrow exhaust.
Lohse
23/41
After paper form and labeling, all systems comply with the legally relevant driving noises. Even the original fails in the MOTORRAD test.
Frill
24/41
Since accessory silencers work according to the absorption principle (with insulating wool), they are usually significantly lighter than the original (with sound chambers).
Frill
25/41
The exhaust tuning is also fun, as almost every system can be installed within a few minutes. A screwdriver experience could hardly be more positive.
BILLION
26/41
Well done, but not a highlight.
Lohse
27/41
12th place: Arrow Race-Tech
The long stovepipe pleases with deep hum on low tours, there is a lack of volume upwards.
BILLION
28/41
There is also a little lack of performance.
Lohse
29/41
The 13th place went to the Hurric Short Rac1 silencer. The Hurric muffler is a bit rough and sounds a bit too obscene for the GS.
BILLION
30/41
In return, however, far too much performance falls by the wayside.
Lohse
31/41
Last place went to the GPR Furore Nero Italia silencer. The GPR damper looks cute and attracts with a low price.
Lohse
32/41
The two operating modes are activated via a push button in the cockpit. Price is 1730 euros (brushed stainless steel).
Lohse
33/41
Here the flap can be seen open.
Lohse
34/41
Tough, but well done. The high-performance exhaust has a valve control. Here the flap is closed.
Lohse
35/41
In a short test, the Kesstech High Performance was examined carefully.
BILLION
36/41
The performance of the SR Racing R 1200 GS.
Lohse
37/41
The SR Racing silencer emerged as the winner. The small exhaust manufacturer in Bavaria is and remains a guarantee for technically first-class systems. And the sound also fits the boxer.
BILLION
38/41
The performance of the Akrapovic damper.
Lohse
39/41
2nd place: Akrapovic slip-on
The one-piece exhaust made of feather-light titanium fits like a glove and gives the boxer an unmistakable sound. Expensive but great!
BILLION
40/41
The performance of the Hattech damper.
BILLION
41/41
The performance of the Kesstech High Performance.

14 silencers for the BMW R 1200 GS in the test
Comparison test including videos on all end pots
Tschingderassabumm, who would have thought: Since 2010 the BMW R 1200 GS with air-cooled dohc boxer engine has been blowing the march thanks to the flap control in the exhaust duct. Which accessory exhaust can put a flourish on it?
Jorg Lohse
08/13/2013
You can literally feel the thieving grin when the BMW official takes a position on the function of the exhaust flap in the manifold outlet: “The exhaust flap, which is controlled by an electric servomotor and opening and closing cables, enables increased back pressure due to the variable passage cross-section in the lower to medium speed range with a small opening and thus more torque and pulling power, while the release of the full cross-section in the upper speed regions is conducive to maximum power, “explains BMW press spokesman Rudi Probst when asked by MOTORRAD. Sound. “

Noise development in the test zone must remain in the green area
Aha, now it’s out. The subject of “sound engineering”, previously widespread mainly on Italian and US motorcycles, is now also enjoying a high priority north of the Alps. Gone are the days when the boxers protteln well and honestly. With the dohc boxer engine, BMW R 1200 GS from model year 2010 onwards a lot of vocal power increased. Thanks to the flap just mentioned, which is supposed to provide quiet tones – when it matters. A look at the European regulation 97/24 / EG, which describes the permissible noise level of motorcycles in chapter 9. The driving noise, which is measured when accelerating from 50 km / h in second and third gear, is of particular legal relevance. 80 db (A) are permitted. What happens below or above is irrelevant. The main thing is that the noise level remains in the green area in the test zone. So cheers to the modern engine management, with which the opening angle of the flap can be adjusted to various parameters such as speed, engine load and gear selection.
Our measurements show how difficult it is to overcome this homologation hurdle: Even the original remains louder than permitted in terms of driving noise. For the suppliers of accessory exhaust systems, the air is getting thinner and thinner anyway. This is also shown by a look at the test bench curves of the 13 systems that compete with the original GS silencer. Very few manufacturers manage to squeeze anything more than the series performance out of the GS. For some, the power and torque curve is almost congruent with the original, some even rob the GS a little of its punch.
At best, they can score points for weight – savings of up to 60 percent are already possible compared to the original pot weighing more than five kilos.

Final evaluation and conclusion
BILLION
The final rating of our product test.
From the screwdriver’s perspective, many accessory silencers are on the winning side, score with great workmanship and chic details as well as easy assembly and an exact fit. But then, on the test bench, the disillusionment follows. For many, the macabre realization of the shortest tuner joke is once again true: Series performance achieved! The times in which a double-digit percentage increase in power output could be expected by simply repositioning the end pot are finally over. Because it is also important to comply with the legally relevant driving noises. And 80 decibels are not a sticky stick, as our test shows. Overall, many providers have done a good job. The best, however, only two that manage to create an almost perfect mix of performance, weight and noise.
Short test: Kesstech High Performance
Lohse
In a short test, the Kesstech High Performance was examined carefully.
A little push on the button, and the good, babbling boxer sound with the flap-controlled exhaust system from Kesstech (Tel. 0 95 28/9 50 05 60, www.kesstech.de) turns into a mighty thunder. The installation should be done by a specialist workshop, as the on-board network is tapped for the electronic control. The result is impressive: In the measuring range (stationary / driving noises) the automatic system closes the flap so that all values remain in the green area. And on the roll, the Kesstech-GS shows a full plus of six percent!
Expensive but well done. The high-performance exhaust from Kesstech has a flap control, which can optionally be ma-
closes manually or automatically. The two operating modes are activated via a push button in the cockpit. Price: 1739 euros (brushed stainless steel).
