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?

Paul,

 Check out http://www.tru-flex.com/truck.html

 Tru-flex appears to be the original manufacturer of the pipe Keith found.
Here's
an exerpt from their web page:

 "Uniquely designed so it will not unwind when cut. Because of our tooling
design,
Poly-FlexTM hose is self cleaning and maintains flexibility longer than
competitive
products. The hose can be field cut by any means and it will not unwind and
does not
require spot welding to hold in place.
Poly-FlexTM ranges in size  from 2" ID thru 8" ID and are available in
galvanized or stainless steel.  Minimum coil lengths are 25 feet.

Applications include: Exhaust hose, agricultural grain transfers, hot air
ducting,
blower hose, conveying shavings, chips, dust, lint and plastic pellets to
name a few."
