"I had Midas Muffeler install the Super 44 Flowmaster Series on My 1998 Grand Marquis. It sounds tough when you start the engine. Not too loud or obnoxious just right. Does not rattle inside the vehicle. When you cruising its very low and deep can barely hear it , but you know its there. I was told to go with the Delta flow 50 series which would have been too quiet and a waste of money. If you have a grand marquis get the super 44 flowmaster series. Deep , rich sound, not too agressive. Perfect 10!!" posted by: buddy810 on December 26, 2007
