Im looking to get an Exhaust system for my 09 FX4 5.4. I want some that won't **** off the neighbor and I can have talk not scream when i am going down the high way. What do you guys have and how does it sound.

Thanks!

I have a 2010 5.4 and have had everything known to man. But by far the best sound and power came when I run 3 inch pipe back to a single in dual out single chamber flowmaster dumped behind cab. Aggressive rumble and but very quit in cab. Helped with my torque and mpg by atleast 1 or 2 mpg

Corsa db - nice exhaust note and zero drone.

I have a 2010 5.4 and have the banks dual system. It rumbles off the line but isn't loud cruising down the road.

Put real dual Flowmaster 44's on my 2007 5.4 3v. No SIDO. It sounds real sweet at about 45MPH but you can talk at highway speeds

I have the Banks single and really like it.

My truck has the factory muffler replaced with a Magnaflow, nothing more. Cheap, clean, deep sound. I love it.

I just got rid of the super 44 that exited the passenger side bc it was way too loud and the drone on the highway was killing my head. I got the dynomax single in single out dumped at the oem location and its sounds great. Has a slight foxbody mustang flowmaster sound without the horrible drone and much quieter in the cab overall
