DO NOT BEAT ME ABOUT THE HEAD FOR THIS ISSUE, PLEASE.
Having built many race engines, I understand the advantage of straight exhaust for horsepower and other considerations.
Does anyone have an idea why a straight exhaust on the Rotax would not be an advantage. Say a two into one dual exhaust.
Almost all smaller aircraft engines run straight.
Less heat in the engine compartment?
Less weight?
Engine breathes better?
Runs cooler?
Gets the oil cooler away from the exhaust collector?
BTW - I have done this a number of times to smaller 75 and 85 continental engines for improved results. It is not difficult to fabricate exhaust systems.
(I have not talked to Rotax about this!)
