Ok guys so I got an 05 king ranch 5.4. I was thinking of just a simple cat-back in the stock location. I don't think I wanna bother with dual rear exits under the bumper, but I do like that as well. I was thinking either the flowmaster American thunder kit or the MBRP kit. I had MBRP on my diesel, but obviously I can't judge from that. And I always loved the classic 40 series sound of a flowmaster. What do u guys think?

I dont know how they sound on a 5.4 but on a 4.6 using a single exit they dont have any sound at all

My opinion is a Borla or Magnaflow muffler. Refer to this thread for my suggestions on the rest of the system:

What I did is had them cut off stock muffler and weld up a Flowmaster Delta 50 series and add a stainless steel 3" tip...sounds great...no drone. $260 out the door.

2.5" True Duals, High Flow Cats, X-Pipe, DynoMax Bulletts, 2.5"x4"x18" Tips 45'd out the rear and be done with it...

Just sounds bad ***!

I'm curious, what is the price range for that setup going to cost me?

MBRP SISO here, great sound without being obnoxious. Got the XP Series T409 stainless for $340 shipped. The 3.5" tubing w/ 4" tip looks nice and mean as well.

I put Magnaflow cat-back system on my 06 Lariat 5.4. Dual Harley style exits behind the rear wheel. Very easy to do yourself, sounds great, not too loud. Cost me about $550 cdn., that's about $8000 US. haha; I know, it'll be short-lived.

X2 on MBRP easy install and reasonably loud (wont kill you on a long ride) but sounds like you got something.
