10) Exhaust system
▲ WARNING: Considerable effort has gone into the design of the ROTAX exhaust
system. Any changes to the original system may severely deteriorate
performance, reliability, engine life, fuel economy and ability of noise
reduction. Improper handling or modification of the exhaust system as
supplied could ruin the engine.
■ ATTENTION: Beware of any accessory systems that advertise an improvement over
stock components.
The exhaust system is tuned for the respective engine and performance and must not be
changed. If modifications are inevitable, then the mid length of inlet tube between exhaust
flange and muffler must be maintained without fail (see ill. 7). For necessary modifications,
ask for manufacturer’s approval in writing. Check engine performance with serial exhaust
system, prior to any modification.

Check exhaust system prior to every flight for tightness, physical damage or changes in
sound pattern. Especially inspect springs and hooks.
10.1) Installation of the exhaust system:
The muffler must be supported on vibration damping blocks. All ball joints must be
greased regularly with heat resistant lubricant (e.g. LOCTITE
Anti-Seize, 297 431) to avoid gripping or seizing of joints and
consequent breaking of exhaust components.
Springs used on exhaust system must be secured against
l
oss and vibration (see Service Information 11 UL 87-E, page
