5.4L exhaust mods - anyone???

[ommegang]

I have a 2008 5.4L. After this plowing season I am going to modify the muffler. I have done so already on my 06 Dakota w/ a magnaflow kit and it has got to be quite loud. I don't wish quite so loud on the 250. At least enough to drown out the belt noise anyway. Anyone modify thier 250 5.4L? Nothing useflull on you tube. Lance

Well you could buy a cat-back, I'm sure there are a handful of brands out there.

Or just go to any custom exhaust shop and tell them what you told us and they'll probably have a mellow tone aftermarket muffler they can weld in place of your stock one.

Best exhaust mod you can do is to remove that big V shaped hunk of iron inbetween the exhaust manifolds...

Will a modified exhaust, in this case no change in pipe dia, just a muffler change, affect engine breaking due to less back pressure?

I think Z was being sarcastic...and saying that the best exhaust mod you could make would be a different engine.

Why dont you do a 22" or 18" MagnaFlow, just replace the muffler and throw a nice 3.5X12 MagnaFlow tip.

I put on a 22" magnaflow on my F150 with the same engine as you have so assuming the stock exhaust is a bout the same mine came with a 32" muffler and there was no sound.
With the 22" I get a nice low rumble while driving with a load on.that should drown out the whine from your belts
While cruising down the highway you will barely notice the magnaflow

^^^ Peladho's sounds great... I would suggest you look into it for a nice deep quiet rumble
