I have a stock 06 5.4 screw. I wanna do a Magnaflow muffler only swap. I want it loud, but not obnoxious loud. I was thinking of going with the 6" round 14" body. Got a price of 65 tax and shipping incl. Was just wondering why most people go with the oval muffler? Anyone have the round muffler only setup? Any help would be appreciated.

 

the smaller 14" is much louder, as the bigger ovaled one isn't, you only hear it when you get on it

 

hey ws6, how do you like the Superchips tune on your 5.4?
