I have a rotax 582 engine that I'm fitting to another plane but the exhaust does not fit. So I've checked a 532 exhaust that will fit.
A. measures the same size and diameter and legths. I dont know the internals??
B.If I use it will there be any known issues?...performance.....reliability?....

I Checked a 503 and I find the same as A above.
And B above ????

Anyone have knowledge on this... please help.
thanks
Andrew

I am no fundi on exhausts, but I know for sure that an exhausts design is critical on a 2 stroke. If you cannot get sound advice on this forum, I suggest that you contact a bike shop that manufactures exhausts, I expect that they will be able to help.

My 503 exhaust was transplanted to the new 582 by the previous owner.

HI Andrew

I have a Rotax 582...at once stage we modified the exhaust (shortened) by 15 mm to make it fit...we had endless power issues...misfire, power loss, couldn't get full revs,.... be very careful modifying a 2 stroke exhaust as they are "tuned" at the factory and as far as I know they work on a specific "back pressure" sound wave.

Speak to Boet Laubscher from Loeriesfontein... ..he is a boffin on this matter...he is on this forum.

hope this helps.

Thanks guys.

Alex Rudd with all his knowledge did the trick.
for information,, the 582 503 exhaust is the same...

Thanks Alex
