So I have two Flow Master mufflers I was given for my trucks exhaust. I stopped at a muffler shop and they put the truck up on a lift and ask me to come take a look. There is no room for the second muffler because of the transfer case and the 36 gallon fual tank. So I left and now I am wondering how do you put a true dual exhaust on a 2010 with a 4.6L in it? Or do I just get rid of the Flow Masters?

you need to go to another shop. obviously, they are idiots. you have to remove the stock muffler and all the piping up to where the "y" pipe is. from there, have them install an "x" pipe. any reputable shop will be able to explain to you the advantages of having this. the flowmasters you have will go in the same location where your HUGE stock muffler once existed. then it is up to you on how to have the tips exit or dump. do a little google research on the "x" pipe advantages.
