> 3 dayInstalled on 12 F150 5.0. Very pleased with this muffler! I had Midas install it (hour and a half). The installer moved the muffler back about 2 from where the original was and sleeved the exhaust from the muffler forward to the cats to lower the sound inside the truck. I had a 07 Mustang gt before this truck and to be honest this muffler made the exhaust sound better and louder than the stock exhaust I had on my Mustang. Deep aggressive sound.

> 3 dayBought this for my 2010 F-150 and I must say it sounds sweet! Nice little rumble when it starts up and during acceleration yet pretty quiet when warm and idling.

> 3 dayWelded & Installed on my 2014 F150 FX4 supercrew 3.5L EcoBoost in the old oem place. Left the resonator on and added an extension spacer on factory exhaust system, this way it doesnt sound like a v6 ricer, instead shes somewhere between an import v6 performance vehicle & a v8 project one has a love/hate relationship with. You know- the ones that get ya sent to the dog house for spending more time with it than your wife & auto parts spending sprees.

> 3 dayThought it was going to be a little louder. However the quality of sound is clean. Clean looking and small.

> 3 dayVery happy with the Flowmaster Super 40 muffler. My Ford F150 sounds great! Very deep tone, but not obnoxiously loud, my V8 sounds the way it should sound now.
