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.
No manufacturer or independent dyno figure found for this specific product. Cat-backs on turbo trucks with a downpipe/tune doing the real work typically carry no standalone gain claim; sound/tone is the primary value prop.
Estimated from comparable claims: MBRP ~+5 whp; Corsa +12; Flowmaster 11; Flowmaster 18
