I've heard mixed reviews regarding the flowmasters. I ended up switching out the MACs for a pair of Borla 11752 mufflers (Street NOT Stingers). Love the new mufflers. Just as throaty and loud as the MACs when I step on the gas. Not as loud at idle. No bothersome drone at crusing speeds. Anyone want to buy my MACs?

I have the MACs and added resonators (Kooks race mufflers) and the drone is 90% gone. It's actually fun to drive now. I remember without the mufflers I used to get nauseated at 2100 RPMs. Good luck!

I have Flowmaster American Thunder series and love them. Sound great, look good, with no drone
