or maybe you didnt tighten the converter bolts as tight as you thought?

personally, i like to thread all 3 most of the way then go around and fully tighten them. i have had them seem tight because the hole werent lined up perfectly and you think its nice and tight but after its running the bolts moved a little and loosened up.

found out what the problem was. the dust cover on the driver side was slightly off. shifted it over and noise is gone. driving the truck now is more fun than ever, but i think i may want a larger stall.
