Looking for high heat hoses

["Jan Schmidt" <jschmidt@kumc.edu>]

A few years back we repaired the fresh air supply tube with a high heat hose. 
It looked something like a half inch heater hose, but was green in color. It 
was rated at 1000 degrees , but has deteriorated and I need to replace it. I 
dont remember where we picked it up at. Anyone shed any light on this one??
Ps I was refering to the catalytic converter fresh air supply
