I plan on putting some 2 1/2 pipes on my 429 in my 77 F-150. What parts do I need to connect my 2.5" flexi-tubing (needed to clear transfer case) to the stock exhaust maniffolds? Collectors, clamps, and anything else. What about this flexi-tubing to the 2.5" glasspacks that I plan to use? Thanks in advance for being specific as possible.
