I have a 2006 5.4L lariat and I'm looking into getting flow master 40 series dual exhaust. Any input on what to do and pricing ideas would be very appreciated, thanks!

I had flowmaster 40 SI/SO... It rusted out... but because you are in Florida, I guess that won't be as big of a problem. Sound was good for the price. Performance? umm... nothing to be noted. I guess maybe some "I wanna hit the throttle and hear the exhaust" performance.

Haha the sound is my main reason for wanting to put them on. My uncle has it on his and said he has a little better acceleration too

I put an mbrp si/do on mine i was planning on flowmaster but the shop steered me away from it. Glad i did though the mbrp catback sounds bad ***

Like my flowmaster at full throttle but between 1300-1900 rpm it has a ton of drone.
