    what kind of muffler?

    I'v got a flowmaster delta flow 40 series 3'' in and dual 2 1/2'' out and i can't stand the popping/rapping noise it makes around 2500 rpm. i'm looking to go 3'' all the way but i havent decided on a muffler. What kind do you guys reccomend? i want a deep throaty sound with NO popping sound and good power

    ive had magnaflow, i have dynomax, ive had flowmaster. out of the 3 the sound of a cammed motor with a 40 series is probably best "muscle sound"

    the magnaflow had a cleaner sound but didnt have the "muscle sound" you hear from the older days

    current combo has a dynomax ultra flow, similar to magnaflow, it quieted down the truck the sound is about the same as it was without a muffler butjust quieter.

    for na the power difference in mufflers is so minoote i would go on sound. Magnapaks are loud if that is what you want

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    i dont like the magnaflow its a little too quiet for my liking and sounds too clean. i had a 40 series on my truck then cut it off and had all 3.5 tubing with a v-force muffle it sounds good. can be a little to loud at times but i like it.
