I have an 2008 fx4 5.4L and looking into new muffler. I want to get a little louder and better tone but not loud enough to hear inside very much. I take it on long trips with the boat so the interrior noise must be kept to a minimum. Any recommendations ??

 

I just posted some vids of my magnaflow setup in my thread.

you can go with flowmaster 44's im not sure what my truck has but it gives it a tone were it gives it that spice it needs but not really loud. even my mom likes riding in my truck. but i like it loud so im actually goin with flowmasters loudest muffler they have witch is the super 10 they are not reccomended for street drivin vehicles.

 

I have a SI/DO Cherrybomb Pro. It's not too loud but people will here you coming. I've been really happy with it. My ole lady hates it but my last truck didn't even have a muffler so STFU!

 

Magnaflow duals. I like mine

 

14 inch SI/DO Magnaflow with 4x22 tips, I love mine, have three little ones that ride in the back and they say they can barely hear it, no drone on the highway but makes a lot of noise when u get on it! Very deep throaty tone to it.

 

Thanks everyone. Those magnaflows are nice. Has anyone used a flowmaster 50 delta flow?

 

Anything is better than flowmaster.

 

My flowmaster 40's sound pretty good. Real low tone

 

A single 40 was on my truck. Idle was ok. Wot was very airy.
