    Mufflers Again

    I recently had the Walker mufflers installed on my '66.  The drone is gone!  I can hear my radio at 65 for the first time in years.  2000rpm is now acceptable.

    One downside.  The idle sound is now a little weird.  I can't explain it - how do you explain a sound?  At speed it is good, though.

    I should have done it years ago.

    “H” pipe, “x” pipe and no crossover all affect sound differently , any of those change?

    Quiet flows?
    Idle does sound different from inside car, but bystanders say it sounds great externally.

    I kept the existing h-pipe.  no changes to anything else in the exhaust system.

    I was listening from outside.  Inside is different, but nothing I can describe as being worse - just different.

    Well, you must have wanted “different” or you wouldn’t have gone to the trouble to change the mufflers, right?

    Right.  And while the drone is gone the remaining sound is also different.  So do not expect the Walkers to only remove the drone.  the remaining sound in all the other rpm ranges will change also.  Idle sounds different too, and quite acceptable.

    One of the reasons for this thread is to give some input for the next muffler thread, when it comes up.

    Did you ever state what mufflers they were?

    Yes, in a way.  They are those Walker mufflers that have been touted as the way to go to eliminate exhaust drone at 2k rpm.  I don't remember the exact number, but they originally went on some kind of Cadillac.    How's that for a foggy answer? (:-)

    Maybe someone can help me out here.  I have had them for a couple of years and all of the documentation is long gone.

    Re: Mufflers Again

    Just got this timely email from Motor Trend, "Magnaflow vs. Flowmaster Mufflers".  The article goes much further on exhaust systems than just the mufflers.
