I am looking into getting exhaust on my 04 fx4 5.4 soon and am asking for some opinions. i am totally new to the whole exhaust package thing but know that i do want to stay legal.. (no straight pipes) i want something that is going to have a good tone at all speeds but will not rob me of any power..


Thanks
Phillip

It depends on what you like, what you want it to sound like.

 

good.. haha i really dont know... i would like it to have a good tone throught the rpms without robbing me of power

 

Magnaflow

Do some research. There is plenty of info here and videos on youtube.

 

I just put a Magnaflow 14" Single in Dual Out muffler on my 06 5.4... It's not an obnoxious idle tone, no cabin drone when cruising the higher, but you notice when I jump on it. I can get you more info if you like.

 

True duals are best but they are expensive, single in/dual out (most common setup) will give you the same amount of power gain as single in/single out. If you want power increase, go with a straight through muffler like a magnaflow, if you want more of a deeper tone, go with a chambered muffler like a Flowmaster. Good rule of thumb, the shorter the length of the muffler, the louder it will be. If you go with a single in/single out (similar to stock setup) make sure you get 3" pipe or you won't see any performance gain, just sound..go on youtube and search different configurations until you find a sound you like

 

If you're unsure of what you want, check out videos on YouTube of similar trucks. There's plenty on there!

 

If you want loud, don't use a muffler. If you want A certain tone and rumble, do as previously advised, watch videos, and choose one that meets your needs. I personally wish I had gone with the SISo setup instead of running duals from a y pipe. To each his own.

 

If u have no budget try magnaflow if not go flowmaster 40 or 44 series.
