Have you seen the Mazda exhaust pipe when running at full tilt?

It's bright CHERRY-RED

My exhaust system approach will be to fit/seal  a 3" dia T304 SS flex
section over the exhaust pipe from the engine to the exit from the cowl.

Such material can be found at J C Whitney for ~ 7.60 /ft.

Hey that's a great idea Keith. I did not know you could get that stuff in 
3 inch diameter. That's a major break through on this issue. Cheap too.

Install a blast tube for a bit of cooling air between the pipes and problem 
solved once and for all.

Assuming of course your down pipe is 2.5 inch OD or less. I wonder if you
can get it in 3.5 or 4 inch ID?
