The exhaust systems from Laser and Sebring for the R1100S are not only beautiful to the eye, but they have also an extremely sound and a decent power delivery. Laser offers for the R1100S a slip on exhaust system made of stainless steel. The axle back exhaust is very easy to install and saves a lot of weight in comparison to the original. Exactly coordinated to the Laser exhaust system is the Tuning Chip for Motronic. As additional accessory you can also install the connection pipe with Lambda connection. Please note, that the omission of the catalytic converter is to be reported to the Admissions Office. Sebring has for the R1100S the exhaust Racer in the program. The Racer exhaust, for left and right, made of stainless steel, offers not only a ingenious look on your machine, but also more power and torque. The second version of the Racer is the change of the pre-silencer by the use of a connection pipe without catalytic converter. Please note also here, that the omission of the catalytic converter is to be reported to the Admissions Office.
