thinking of putting a flowmaster 44 series on my 04 f150 5.4 3v. good idea or no. my other choice was the 40 series. but thinking of the 44. second question is should i go catback or pull the cats. can it be true duals or does it have a y pipe. i called a shop and they said i have to bring it in for them to tell. i think they just wanted me to go to them.

 

Yeah, they just want to get you in the door.
