Flowmaster 40 Series
I have a 03 Mustang GT Convertible and I want to add a flowmaster muffler. It's the 40 series does anyone have an opinion on this muffer. It's my first mustang and right now it's completely stock but I'm hoping to start to change it.

RE: Flowmaster 40 Series
I have Flowmaster 40 series and love them. Deep rasby muscle tone, beautiful idle and not obnoxious at high RPMs.
Take note: Flowmasters drone, so I hope you don't have backseat passengers.
