You have to buy mandrel bent els. Most muffler shops don't do mandrel bends. When you cut through non-mandrel bent els, you will have an egg shaped hole, not round. You won't be able to line this up properly with the next straight or partial el. Mandrel bent els have a virtually round cross section through the bend. That will allow correct alignment with the next piece.
