Run the pipe under (ugly and hurts clearance) or through.
You can open one hole in each leg to get more room, but under the driver's side front has lots of stuff taking up all the room.
On my 40, I had them do a single and run it under the pass front leg and through the rear leg. This is like stock.
I've got a 5.2L magnum, and figure that it won't be seeing 4000+RPM much, so a single was easier to do.
