Removal Procedure
Tools Required

Caution
Provide additional support when a vehicle is on a hoist in the following ways:
Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.
Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.
Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.

That SOUNDS like it is a PITA

Not really sure why you would have to take the muffler off, unless you can't get your arm/hand up to where the cross over tube/s are located.
Anyone done this that can give a "difficulty level with the car on jack stands (as opposed to a rack) and time it takes to complete?
Thanks
