Engine out can I install Dougs beforehand

How did you do it? Mine looks like its not long enough to move very far. It was also suggested to run them between the tube that splits away for the header and the other pipes.

We just pried them out of the way with a screwdriver, being careful not to pinch or kink the lines...

Then on the one, we had to straighten out the "loop" at the end some to get the extra length that we needed...
