Flowmaster's Flow FX line uses a straight-through muffler instead of their classic chambered design, giving a milder, more modern tone than their American Thunder/Force II/Outlaw lines. Dual same-side exit means both pipes exit together out one side.

why this one — Flow FX is Flowmaster's mildest-sounding option, here with both pipes on the same side, for buyers who want a flow improvement without a loud, aggressive tone.
