This Rotax exhaust is designed specifically for this ROTAX MC 100 ulm

it is designed to be installed in the upper part of the engine; in fact, hoods are confined around the engine

there is no place to put it elsewhere

it allows :

a 5% gain in power
a gain in consumption of 10% for the same performance
a 50% reduction in vibrations
an acoustic gain of 5 dbs

• un gain en consommation de 10% à performances égales
• une diminution des vibrations de 50%
• un gain accoustique de 5 dbs

This is a dyno test  work that allowed this optimization.

It is available in stainless steel 316 L

Mais également en Inconel 625 . Dans ce cas le gain de poids est de 40 %
