03 ford f150, v8 triton, w/ cold air intake, throttle spacer, & flowmaster dual exhaust.
My question is, when i start it up in the morning, sometimes it will sound loud, and rumbly at any RPMs, (like any truck with flowmasters should sound like), and then other times, it will be very quiet, not much rumble, maybe a little at 1700-1800 RPMs.
Today, i noticed that about 20 mins of straight driving it warmed up and was roaring..it ran very good, nice clean loud rumble upon acceleration. Even when i went back home, waited about 45 mins, then started it up again, temp gauge at half, it was roaring very loud. Why is it that sometimes itll be loud, then others it isnt? I never know, because it could not be warmed up yet, and be loud, and other times it wont. It could also be warmed up, and sound very loud, and other times it wont?
How can i fix it if its a problem to the car's engine?
