Performance Header
The original header pipes are the greatest obstacle to
a better performance. Our system has carefully put
together to get the best possible solution, special atten-
tion was given to the gas flow and smooth transition
between the components.
The facts:
• Performance increase up to 14 HP (with PerformanceControl-
ler).
• Significantly higher and more harmonic torque.
• Enormous weight saving (comes without interference pipe and
collector).
• More powerful sound (approx. 5 dB (A) more).
• Optimised pipe routing.
• With provision to bolt the oxygen sensor in (no modifications of
vehicle).
• Straightforward installation.
• Made of strong stainless steel material.
• Matched to original and Wunderlich silencers, but other silenc-
ers fit as well.
No TÜV approval, so only for racing purposes. Original
motor guard must be modified or removed.
R 850/1100 GS
Complete stainless steel 3 piece-system system, spring
mounted.
Part No.: 8600420
Remus Exhaust Holder
Exhaust holder of the Remus silencer, suitable for the
models R850/1100GS. Necessary if you would like to
combine a silencer from Remus in connection with a
"light" collector (our Order no.: 8600175). The 8600080
and 8600087 collectors are supplied with a suitable
holder.

Wunderlich Sport Collector
If you really want to save weight and still want to find
the odd one or two extra HP, you will be able to get a lot
from this sport collector:
• Enormous weight saving.
• More powerful sound (approx. 5 dB (A) more).
• Uniform performance.
• With Oxygen sensor connection (=can also be used on cat.
vehicles without alterations)
• Straightforward installation.
• Polished V4A.
• Suitable for original or accessory mufflers (not R 850/1100 GS*).
As the performance-restricting catalytic convertor is
removed, this collector makes a good basis for all fur-
ther performance enhancements. Without TÜV. Only for
sport purposes.
R 1150 GS + Adventure
"Professional" type
Very lightweight and perfectly coordinated collector. The
lack of the catalytic convertor is most noticeable here: a
rich increase in torque over the entire speed range. The
GS becomes permanently stronger, particularly between
3000 and 5000 RPM and is given a deep, sonorous Box-
er sound (even with the original silencer). According to
our measurements, the best collector for the GS – also
first choice because of the quality (stainless steel) and
the machining. The precisely-calculated chamber vol-
ume reduces late ignition in the muffler (overrun "pop-
ping") and are in perfect harmony with our sport exhaust
units as well as the original exhaust. Weight: 2.9 kg**.
Part No.: 8600032
** For comparison: The original weighs 7.2 kg.
"Sport" type
Minimalist stainless steel collector with only 2.4 kg
weight. The absence of any chambers in the collector
may cause occasional overrun "popping" noises. ABE
approved in connection with Revolution Supersport
silencer. Weight: 2.6 kg**.
Part No.: 8600099
R 850/1100 GS
Sport Collector
Without taking any further steps, (such as tuning chip),
the original drop in performance between 3500 and
4000 u/min is slightly increased. However, this is not
noticeable during riding. Weight: only 2.5 kg (Remus cat.
collector: 5.9kg).
Part No.: 8600175
* Not suitable for original mufflers (Inseparable unit with the col-
lector)

Remove the catalytic converter?
No problem at all! We only ever sell collectors with built-in oxygen sensor
connection. As far as the sensor is concerned, it does not matter whether
a catalytic convertor is present or not. The main thing is that the sensor is
able to measure something and transfer this information to the Motronic.
The unit can therefore be exchanged without any problems/hazards. The
lack of a cat. is often crucial for increased performance and the use of
lower quality petrol.
