i am going with the 14" magnaflow single in dual out with 18" x 3.5 tips,rear side exit. i dont want it real loud, but i want it deep and mean sounding when i push on the peddle. should i go with the 18" muffler? it is on a '03 5.4.

 

Thats the muffler I went with on my 03 5.4 screw. I had fake dual out the back with dual tips each side. It wasnt very loud at all, but had a nice deep sound. I always wanted louder though...

 

that is exactly what i have an '03 screw. i dont want it very loud, i want it louder than stock. how does it sound at idle?
Bullitt,
i seen the pics of your truck from your gallery, it sure was a nice truck.
have you installed your ravin exhaust yet? how does it sound, and look?
