The rubber air hose connecting to my Bonez Cat is completely split and needs replacement. The original hose lasted a long time, but the replacement hose I used didn't last very long. When I replaced it I used whatever fit which I think was a water hose. I guess it can't handle the heat generated. Autozone hose I don't trust either. What type hose do have you guys used??

Here's pictures of where I'm talking about. Thanks.....

 

try to find some small diameter flex steel line.

anything rubber will eventually get cooked.

 

I hooked mine up with heat resistant silicon hose.

7 years ago.

 

I finally started my car after the rebuild and it started, thank goodness, but I have a temporary rubber hose connecting the Bonez cat to the air pipe. I like the idea of silicone hose, but I see ratings are only to 350F. Is that good enough? I would think around the cat it would be near or more than a thousand degrees.

 

Find a flange off your old cat and an extender pipe.Weld the flange to the cat.That will dissipate heat through the pipe.
