Default Muffler question

Hey guys,
I ordered a flowmaster 40 series muffler and the stock muffler in my 99 f150 is longer in length than the flowmaster is. Does this matter, or when you remove the stock muffler, the pipes are longer than what it looks? Also it seems to look as if the stock muffler is welded on, and I have no cutting tools, not really sure what my best bet is. Should I take it to a shop? Will I need to buy myself some clamps?

You'll need a filler piece of pipe to make up the difference and the old muffler has to be cut off

Not sure why flowmaster would say the fitment is for my year and model if I need to buy extra piping...
http://www.autopartswarehouse.com/de...QF1342543.html

http://www.flowmastermufflers.com/sh...le=&orig=42543

both of those websites say it should fit.

You spent the money to buy your self a good muffler,so don't cheap out on the install if you don't have the tools to do the job!
Take it to a shop have them install it. They will weld the seems and add a piece of exhaust tubing for a leak free exhaust.
