1995 Air Injection Issue

So first off my secondary air injection check valve had broken before i bought the truck and didn't know. I finally got a new one after searching and waiting for a warm day to replace it, went to take the rest of the broken one off and the crossover pipe snapped in half...go figure. I found a replacement crossover but my issue is i can not get the old one off, the bolts are ridiculously tight and i actually bent a wench(cheap old one) trying to loosen it. My question would be what is the harm in a few things, A. Leaving it how it is, broken in half. B. Running a rubber hose from the two broken ends of the pipe as a redneck make shift fix. C. Capping it off the right way. Or if anyone has any suggestions on how to get the bolts off. There is very little room for a socket or anything to get to the bolts which makes it even harder....Anyone provide some advice?

Thanks

You can't leave it open that constitutes a large air leak in the exhaust upstream of the O2 sensors which will cause serious engine issues. So anything you can do to seal the system up including adding some rubber hose to reconnect the system(it would have to be silicon hose actually as the exhaust gasses are still very hot), or best of all get the broken bits off and install the new crossover tube.

Did you access them from top or bottom, or one from each? If not, did you use silicone hose? Anything you wish you would have done differently? Any help would be appreciated.
