I am putting true Duals on my 05 F150 4.6 and i cant decide between the original 40 or the super 40. can someone please tell me which would sound better and give me more power. Thank you

 

Ive been looking at various exhaust lately too and one of the best things to do is go to you tube and type in things like f150 4.6 exhaust and youll get tons of videos of different set ups people have used

 

ya i did and i couldnt find any with true 40s or super 40s so i was just wondering how many people have them or have heard them on this kind of truck

 

The super 40 will be louder and as for power, they are both going to be similar. If you want power go elsewhere other than Flowmaster. They are better than stock, but are more restrictive than other exhausts out there.

having said that, I have the Super 40 and love every aspect of it.

 

anyone have anymore suggestions??

 

Magnaflow. They are straight through and sound great.

 

in my opinion the magnaflow works better and sounds deeper with better flow threw and i have read else where that the flow master is more restrictive than stock

 

The flowmaster's are not more restrictive than stock. And as for HP differences there will only be a 1-3 HP difference at the wheels anyways so go with what sounds good unless you want that minimal HP gain.

 

^^^Agreed. I'm more concerned with sound over performance which is why I went with Flowmaster and I love the sound!!!

 

Original Flow 40 on my truck with a 5.4, sound's great, loud when you hammer down but at crusing speed it's quiet.
