<<Stainless for some applications is good but I doubt that you've
improved much by going to all stainless on all engine fasteners.>>

Stan,

All the exhaust component's from the heads to the tail pipe are now
stainless steel fastener's.

This is where I was originally pointing with the corrosion resistance of
the stainless, nuts, bolts, and lock washer's.

The exhaust system takes the biggest beating from rust, heat, and the
wheel wash, and I want the system to be serviceable at a later date,
with the least amount of effort.

 I will get this with the premium choice of stainless fastener's I
decided to use.

I hope nobody read anything else into the original thought of how I
chose to improve the exhaust fastening system.

No other engine components were in question here..
