Which is the best flowmaster?

[eeh1025]

If i were you i would go with the flowmaster 2 chamber 40Ser delta flow. i have tried regular flowmaster 2cham 40ser Dynomax,Magna Flow and i even tried the quick flow mufflers i called up and ordered them. and the best dyno result i got was the flowmaster 2 chamber 40Ser delta flow. the sound on them is great its louder then stock but not very loud, but when i get on it then really open up are loud that show true power. i would go with the flowmaster 2 chamber 40Ser delta flow. i had the best results with them and better hp.
