It's suppose to be good to 350F continous operating temps so I figure it should work? I don't think temps at the injection pipes on the cats are above 350F? If so I guess I could wrap the pipe at the cats in some header wrap or some other form of heat resistant material. I'm only gonna have the cats on while I'm getting my car inspected so I figure it should last long enough for that.
I have one that I used to use to pass smog, but my state doesn't require smog anymore on '95 and older vehicles so I removed it a few years ago and it's sitting in the corner of the garage along with the black hoses and diverter valve that comes off the back of the pump. I think I used a piece of high temp silicone hose to connect it to the cats. I don't run a smog pump anymore either, and have a mechanical crankcase evac pump in it's place.
