Hi Ken, well I never got to the 150 hr mark …
Your exhaust on the rotary looks about as simple as they come.
How is it for noise?

I had a belt drive on the Ford V6, belt was about 6"
wide; had to buy a custom-order, set of 4 - could not buy less © set was $320
or $80 each. No idea about the actual service life but at that time people on
the "Ford list" were expecting to reach 2000 hours.

From what I've seen so far, ALL cog belts, doesn't matter
what size or what HP limits, have a very safety concerned operating limit of
500 hours/2 years, whatever comes along sooner, even if they still LOOK almost
brand-new. This was stressed on all belt PSRU sites (for fixed wing or rotary
wing).I've not seen replacement belt prices because they have not been posted
and I have not asked.
I have run a cog belt on my Rotary Coot for about
1000 hrs now and I replace the belt about every 150 hrs just to give me that
warm fuzzy feeling, I am using an Opit Omega belt and the cost is about 100
bucks.
