I'm just about set on ordering Flowmaster mufflers for my 06 GT. My question is do they have any noticable drone at any speeds? I can live with a little drone, I drive a lot of highway miles at speeds of 65 to 75 just wanted to know if they droned bad or not. I love the sound of the Flowmasters I have a set on my 75 Mustang that sound great.

 

I just install Flowmasters on my 06 GT today. I haven't driven it much yet but I'm already glad I bought them. They sound and look great with only a little drone.

Search the 2005 Mustang forum for "Flowmaster" to get others opinions also.
