Trying to remove my downpipe but I can't get the bottom two bolts out. Tried penetrating oil and heating it up. Heating it up seemed to cook the gasket, so I stopped that. Not a lot of room for extending my box-end wrench, and not enough space to get a socket and breaker bar. Any advice would be appreciated.

Bolts are circled here

 

Only option is crows foot. I remember way back in the day when I had that **** I just used multiple open box wrenches to get them off and a lot of pb blaster
