Sounds great on my 4.0L Straight 6 Jeep... but once again I don't think its one of those mufflers for a 2.0L focus unless you are of the kind that like the sound. its personal preference but that muffler does not belong on any 4 cylinder motor.
You can find comparison videos on YouTube between the Flowmasters and MagnaFlow. Honestly, between listening to the two I didn't hear a difference. I went with my MagnaFlow because it was stainless steel so I could run it year round without it falling off, it was cheap compared to everything else I could find considering it was lifetime warranty, and it was free shipping and handling.
Flowmaster uses a welded chamber design for their mufflers, instead of a straight through design with sound dampening media. Completely different muffler design than Borla, Magnaflow, Etc... Like the other guys said, they sound great on larger displacement engines, but not usually on 4 cylinders.
