What about disconnecting the exhaust? It's it that hard to disconnect the exhaust mounts and flange and leave it on the ground under the car. Next morning start it up with just the DPs while a buddy watches underneath. You should know one way or the other, and it just costs a little time and one set of flange gaskets.
