i would start by disconnecting the muffs from the h-pipe since its only 4 nuts total.
then loosen, but not disconnect the h-pipe to headers nuts (i think 15mm) the h-pipe will still be in the tranny mount, but shake the h-pipe so its not stuck on the headers.
then tighten the nuts on the header flanges EVENLY. if you tighten one nut only 3-5 turns with the ratchet, do the same with the other nut. repeat for the other side of the h-pipe.
*how bent are the flanges on the h-pipe??

also, autozone has some flanges you can pick up that are 2 1/4" if you have a stock h-pipe or they also have 2 1/2" if you have an aftermarket h/x-pipe

well there should be studs on the headers. the h-pipe should have flanges. when u put the nuts on the header studs, they should pull the flanges that are connected to the h-pipe closer to the headers. you almost HAVE TO have flanges. if you can post a pic --rick

it is a ball and socket flange, there is no gasket used.
