I hate to be the one who bursts the bubble, but in my opinion, Flowmasters are overplayed. Sure, they might sound good, but they also sound generic. Who doesn't have Flowmasters? JBAs are nice, but it's only an axle-back. I have Borla on mine, and I can't tell you how many Mustang owners (with Flowmasters) have asked me what kind of exhaust I have. The sound of the Borlas is much more "tuned", not a lot of noise like the Flows. That's my insight on Flows, but some might disagree.
