Meanwhile, I've added .01" stainless heat shielding between muffler and

engine

and between carbs and muffler and want to add stainless on the inside

of the

cowling near muffler and exhaust. Aluminum does not stop a direct blast

from

cracks in the muffler. I cut through one of the header pipes and put

flex pipe

over it. I hope that's enough to prevent cracking from muffler

expansion and

contraction.

This was really the primary reason for my exhaust system design - get the
heat out from under the cowl as soon as possible. Cuts down on the
potential for damage done by a blow out, reduces the need for heat shields,
and hopefully will reduce the cooling system demands.

Good thinking Mike. If I go with the stock turbo on the Cruiser
I will bring the exhaust 180 degrees out the side of the cowl near the front.
The turbo turbine would then be near the front and the compressor near the back.
It will look like it has  a mini PT6 :-) I am working on a drawing now.
