I have a 03 F150 FX4 Screw w/ 5.4, and I want to make it a little louder. I don't wat a catback I just want a muffler welded into the stock catback. I was thinking about getting a Flowmaster 50 series. What do you guys suggest? And if you have a clips of vids, please post them up.

Thanks.

 

i second that i have the same truck and was thinking bout maybe doin the same thing.

 

the 50 series is what i was thinking of as well. sounds good but not too loud. go to the flow master website. they have details and a sound clip.

oaw

 

Magnaflows seem very popular here. I am going with the #12226 muffler that was suggested by several different people.
