i have a 2007 F150 Scab and was wondering if flowmaster duals out the back or the magnaflow duals out the back were better

 

Magnaflows are better if your looking for performance.

Keep in mind , the shorter magies are louder..

 

nice cause i was lookin for performance and somethin with a nice tough sounding rumble at idle and a loud roar when accelerating

 

if you want a nice rumble on idle, go with the 14" Maggie muffler. I run the 18"s and on idle you can hardly tell its not stock. I still have the stock cats for the time being though.

 

Yeah , Kev has a nice set of 14's DIDO - There kindaloud from what he say's.

 

Ya the 14's are loud in a true duel set-up.If you go true duels keep the pipes 2 1/4 inch all the way back.I also recomend putting an X-pipe in there to balance it out a little better.If it's still not loud enough replace your 4 converters for 2 high flows.
Keep in mind i used to have flowmasters and i know how loud they were.
oh and mufflers cheap here www.performancepeddler.com

 

Magnaflow.

 

Yeah , I have the SISO W/24" Magnaflow. Love it!!
