Dynomax muffler rattle?

  1. I heard today that some of the Dynomax Mufflers come apart inside and start to rattle after a little while of use... Anyone had that happen to them?
  2. I heard a rattle in my flowmaster muffler and thought i was gonna have to buy another one.. then i got a magnaflow catted X pipe and the sound was gone ever since:shrug:

    wierdest thing.. but if you haven't changed midpipes yet, that may help

  3. I've ran Dynomax mufflers in the past and never had any trouble with them. I had the welded ones with the heavy cases ... they weren't real loud, but had a good sound to them.
