does anybody know where i can find a di/do flowmaster 40,original 40 not a delta flow?or even better a part number? i've looked on flowmaster's web site and everywhere else i could think of and can't find one.i remember seein one a few years ago in a catalog.i need one that's 2 1/2 too if anybody knows of onethat size.i apperciate any help

 

i have 2 flowmaster original 40's i had the same problem, except fiding out what kind they were since i bought my truck from a friend. the part number is 42441 Flowmaster ORIGINAL 40 series. hint if you have a v6 like i do 4.2 v6 with dual exhaust and true dual exhaust here, its not sounded as good as ytou would think, but it still turns some heads.
