I got a 2005 Ford F150 5.4L. Im looking for the loudest and best sounding Flowmaster muffler. I am not going to touch the cats though or mess with glasspacks. If anyone has sound clips that would also be appreciated. Thanks for your help.

If you want loud with cats, just cut out the muffler, and straight pipe it

 

X2 ^

 

Im just not sure what straight piping sounds like.

 

Sometimes the straight pipes will make a poping and crackling noise while on my friends F150 they sound fine and are LOUD. Ive never seen or heard of what he has tho. Its one pipe coming from the cats, if he has them, and then it splits into two pipes right before the axle.

 

straight pipes on a ford will sound like a system with mufflers on a chevy.

the best part is that it only costs about 9 bucks, 12 if you clamp it in.

 

Thanks fellas I'll try both.

 

if you stand behind the vehicle, it will sound like a loud diesal, and yeah its nice .. you will hear it in your cab, and if you have the music up, you will feel it in the seat and accelarator... its nice
