I've got a 2010 F-150 XLT with the 4.6 V8. Just curious what my options might be with going to a dual exhaust system? Is it as simple as adding flowmasters/magnaflow mufflers after the catalytic converter? Is it even worth it?
Not worth it at all if you think you are going to gain performance. If you just want a nice rumble, just add in the Flowmaster, Borla, Magnaflow etc in place of your stock muffler. Keep it a single exhaust. It will sound great. I did it to my 5.4 in My Expy. Great sound and it was relatively cheap.

IMHO, the 4.6's sound better than the 5.4's with a nice exhaust.
as said above, do it for sound, and nothing else
go for a stainless if you want it to last. if you do a full custom exhaust, plan on doing it every few years unless you can get them to use stainless, which they won't. or get a full stainless kit.

i have a 2010 STX 4.6 2V with a flowmaster single in/ duel out 50 series muffler. If i had to do it again i'd have just removed the stock muffler and put in a single in/ single out, as my left tailpipe keeps sagging due to contacting the leaf spring when my tires get rotated.
I love the sound of the 50 series but it's a little loud to me at times, but the wife loves it, so i suppose it's going to stay. next time i'll go with a 60 or 70 series... perhaps it's because i'm getting older that i don't like it quite so loud. I've had it for 3 years and no issue with it rusting out like many will say. there is a little rust on the welded seams of the pipes but i expect that.
hope this helps,

I made this video to show a friend my new setup when I bought my truck. Full stainless Flowmaster dual for $300 out the door from Meinike Car Center. And yes it did provide some performance and MPG from what I noticed stock. Not crazy amounts but enough to notice.
Go Magnaflow or Dynomax Ultraflows... Sound better, flow better, and last longer than Slowmasters. Still, you won't gain anything over stock with simply a cat back system, other than sound. I like the '09-'10 stock muffler sound. Just enough throat, and quiet when cruising. If I want loud, I drive the Stang or my bike.
