If you cant get the lengths/bends in a one piece simply 2. Manual shows both a straight or 90° connector available to adapt muffler to tail pipe, but doesnt show tail pipe extension.

http://www.norwall.com/product_pdfs/626_2.5hgjbb.1121.pdf • Exhaust kit elbow 90 degree (P/N A041H694)
• Exhaust kit downtube (P/N A041L816) 5.75" lg
Manaul shows the above which are flanged down tube connectors. With a straight down tube then add section with 90°.
However available 'kit' 155-2325 shows a split clamp on- what it doest show is if it clamps directly to gen or to downtubes above (which I suspect is case-extension clamped to bolt on down tube)?
