Hello, I have a 2007 Expedition limited with the RSC 4wd system. I am looking for an aftermarket exhaust system for under 400 bucks. I want it not too loud but still have a nice rumble. Thanks!

 

my preference would be to get a 22"/24" Magnaflow muffler with a 5 x 11 body.. I like the straight thru design (less back pressure) and the quiet rumble under idle and normal driving...then when you get on it...a nice roar... I've gone different brands and sizes...after awhile you appreciate the quiet muscular tone that a bigger aftermarket muffler gives you when you drive normal...
