Hey guys, I just got an 07 f-150 and the first thing I wanna do is put a muffler. I'm leaning towards Borla...maybe magnaflow, my question is....what would be the best bang for my buck? A true dual? Dual in,dual out? single in, dual out? And what size measurement would be best?

 

I'm sure there is a bunch of info out there already, I am also interested in a muffler and am having a tough time deciding. love my prior experiences with flowmaster and didnt love prior experiences with dynomax, and have a buddy that loves magnaflow
