Heat riser flexible hose source

Mine are deteriorated. I am looking for the one that goes from the exhaust system to the intake to warm the carbs.

Thank you.

Do a search for "SCAT"

I just replaced mine and it's surprising how warm that heat riser duct gets idling in the driveway.

Thanks Bruce - that looks like it should do the trick. What diameter and length did you use and were you happy with the fit?

I got from Autozone. It's Spectre brand.
