Do (Long Tube) Headers Need To Be Supported @ Collector?

Do (Long Tube) Headers Need To Be Supported @ Collector?
I seem to recall hearing that headers need to be supported even when running open headers, or it will crack a weld on he header? or distort?.. Is that the case?. What about with exhaust hanging off it?.. Currently I have the front half of my exhaust being held up by the header, no hangers at all other then the rear. Is this a no no?. Do i need to take the pressure off by adding a hanger to the collector? Thanks

LT1s don't need backpressure, they need enough pipe behind the O2 sensor to keep fresh air off of them between exhaust pulses.
Pretty much nobody supports headers, yes in stock applications there is usually support near the tranny BUT that also has to hold up a converter and 100K mile emissions warranty.
On the b-bodies it is routine to throw away the exhaust support at the tranny leaving the exhaust supported at the engine and then at the rear of the mufflers which is basically at the axle, think about the length and therefore leverage and weight.
