Anyone has this problem?

Well i have a 1994 F-150 XLT and i notice that my motor is loud, its not as quiet as it used to be a long time ago, my grandpa has a F-150 1995 XL and i took a drive on it this weekend and it was quiet compare to my, when i gave it gas i didn't hear the motor that much just normal like how mine used to sound, i thinking that its a leak on the manifold where the muffler goes out from, but i took it somewhere and they said they didn't find anything, where else to look, i rather hear my muffler then my motor.
Any help you guys or advice

Was it just loud or did it have a popping or hissing sound?

Well I thinking it's my exhaust but I gotten people to check on them but they find nothing. Like in idle it sounds ok. But when giving gas it loudEr then the 95.

Its probably either an exhaust leak or the fan clutch. Does it sound like s school bus? If so, then its probably the fan.

If its a more constant sound that increases with engine speed then fan clutch. If it is a pulsating sound or hissing sound that increases with engine speed then exhaust leak. Its hard to say with out actually hearing it.

if you are looking for an exhaust leak... the good old test i use is to have a buddy put a leather glove on and put his hand over the tail pipe so the gas has to be forced out somewhere else... while he's doing that i am under the truck listening and looking for the leak.

When the motor is off & cool spin the fan with your hand & see how it turns , when its hot it will be harder to turn . If the clutch is locked up it won't turn or will be hard to turn....
