Cracked manifold TSB??

Finally got around to a new hi flow converter and 02 sensor, also welded up the crackd header, Made quite a bit of improvement, feels crispy again.,and pulls hard up the grades.(95ho) Muff man said there never was a recall on cracked manifolds he heard of only pricy replacements from jeep and they were prone to cracking also. Is this true? Im sure it just a matter of time before mine opens up again. I was under the impression they replaced them to new owners under warranty.

I'm pretty sure Chrysler never owned up to the fact that their tubular manifolds were prone to cracking (due to how they welded then bent them stressing the metal).

Youre going to have to take it like a man and fix it if it breaks again.
