Customer Review: (see review/s)
  • The muffler fit well and sounds nice. Interior noise was less than I expected.

    posted by: Jim on August 11, 2008

  • I HAVE A 1969 Z/28 CAMARO WITH THE FACTORY 302 SOLID LIFTER MOTOR. THIS WAS A GOOD CHOICE FOR DUE TO THE FACT IT HAS A FACTORY EXHAUST SYSTEM ON IT. I COULD HARDLY HEAR IT RUNNING, SO I UPGRADED TO A 80 SERIES FLOWMASTER. THE ORIGINAL MUFFLER WAS CLAMPED TOGETHER SO I REMOVED AND INSTALLED THE 80 SERIES IN ITS PLACE RECLAMPED IT WITH A LITTLE EFFORT AND TIME. IT SOUNDS GREAT THROUGH FACTORY EXHAUST MANIFOLDS..
