Load in the bed with stacks

[SSabick]

Ok, I finally have a chance to get a set of stacks that I have wanted since the truck was new. Wife gave the ok, and money seems to be in place, but now, the sensible side of me keeps asking how I will be able to haul dirt bikes, firewood, and hay for the horses? Is there something that can be done to take the stacks out plug the hole, and turn the exhaust out to make the bed usable again? I realize that my tie down anchors are useless once you cut the hole in the bed, then cut out the pice of cross support, is there something that can be welded in to keep some strength there to tie down a dirt bike? I really want them 6" miter cut stacks, but I need and use the bed sometimes also. Firewood would no doubt crush the pipe, and the stack heat would scorch, or catch fire to the hay that I have to get about two times a month. any advise?
