[W126 Coupe] Exhaust coatings

[Jim Nowak]

I don't think it's valid comparing an engine that
turns at 18,000+ rpm to one that turns at 6500 rpm. 
Keeping the heat in the exhaust does increase the
exhaust velocity as does using the correct size
exhaust plumbing for your engines output.  Exhaust
plumbing that is too large will slow your exhaust
velocity and rob you of power as does exhaust plumbing
that is too restrictive.  Not to mention, keeping
excess heat from your engine bay helps your engine run
cooler.
