Loud noise in pipe exhaust due to humidity

Recently I started to hear a loud noise by the engine from the exhaust pipe I do not see any loose or broken pipe, a friend told me that it might be due to the humidity, where I live the snow was about 40 inches high and I had to go out every day so I was driving over the snow four-six times every day will this noise go away by itself or do I have to do something ?

    Thank you for your answer, and yes, the noise did not disappear and I have to replace the flex pipe from the exhaust and the noise is gone.
    Now I have another problem, last Saturday I changed the throttle posi
    tion sensor and now the car is running very rough, hesitating and the RPMs are going up and down, a friend told me that the computer is learning the problem has been fixed that is why the is car is acting like that, its this true ? will the car be running smooth again anytime soon.
    Thanks, Carlos.

    Absolutely, previously I heard that every time I change a sensor I have to disconnect the battery but I was not sure, so I will do that as soon as possible and thank you very much for your advise, I am sure I will be OK.

    up and down, can you tell me please for how long this has to keep going before come to normal.

    Thank you

    the noise will not go away by itself, and it is not due to humidity.

Did u disconnect the battery after the sensor was replaced? if not u will need to do that so a new base idle setting can be learned by the computer, it is called adaptive idle strategy.

Loud exhaust noise on startup

2008 GMC Envoy is only equipped with one of two engines:
4.2L (254") 6-Cylinder SFI
5.3L (325") V-8 SFI

Niether of these engines are equipped with an EGR valve, so I guess the probability of that being the cause of your noise is pretty much zero to none.

If you believe the noise is being caused by the exhaust ststem, then the only way to verify that is to inspect the exhaust system. Leaks are easier to verify with the engine running.

With that said, there is also a Technical Service Bulletin (TSB) that is published by GM that addresses customer complaints about loud noise that is being caused by the electro-viscous engine cooling fan clutch. Some people describe it as exhaust noise and others describe it as the engine "racing" or "roaring".(even though the tachometer (if equipped) will be reading normal)

It basicly says that it can make noise on startup due to high rpm of the fan which goes away once the electric solenoids open and allow the fan to start free-wheeling. GM says this is normal operation. You might want to check to be sure this is not what you are hearing. (it can be pretty loud)

There is a tube on the "side" rear of the engine that leads to the front. Into this tube are loosely place saller tubes coming from the engine. This tube appears to have snapped. Would this...

the tubes i think your talking about have to do with emissions that supply fresh air to the exhaust for those cylinders when required.if they break off you will get an exhaust noise which is what your hearing.there are only 2 ways to fix is to repair/replace the damaged pipe or remove the pipes and plug the system aware if you do the last it will fail an emissions test and have to be replaced to pass anyways.

The pipe is making loud shaking noise

which pipe, i assume you are referring to an exhaust pipe, do u have a loud (more than usual) exhaust sound, if so, the exhaust pipe is cracked or split, if not, then the exhaust hangers (mahe of heavy duty rubber) are split/broken, causing it to shake OR is the engine shaking as well, or just the exhaust, too many questions, need to specify

This seems to be a classic case of "disentegrating exhaust system syndrome." There is either a hole(s) somewhere in your exhaust system or there is a leak somewhere. Probably the easiest way to tell where the noise is coming from is to start your car and just listen around in the engine bay, under the car, and at the muffler. Also do a visual inspection of the exhaust system to see if you can see any holes in the piping. I have also seen hairline cracks in the exhaust header itself that can cause the loud ticking noise that can be a little tricky to track down.
