I think I kinda pushed my car too hard. I was at the stop light at the bridge and when the lights turned green I Mashed the gas pedal and went shooting over the bridge. A few hours later when I got in my car and began to drive off, I heard a sound like a very loud buzzing from a Hair trimmer almost sounds like its coming from the muffler exhaust area. It's there for the first few minutes of driving then it goes away until i turn the car off and turns it on again after sitting for a while. The car drive fine and all not roughness or anything. I'm just curious to what that sound is and if anyone experiences the same thing

 

Check your exhaust gaskets, you might have blown one.

 

Werd

 

^^ It's possible that it is simply leaking and once it warms up and everything expands that it's fine again.

 

I see no leaks, but its just the weirdest situation i've encountered with a car. The noise is more noticeable at the left exhaust tip.

 

Do you have a stock exhaust system or some aftermarket system?

The stock exhaust is actually a single from the cats to the rear muffler. If the sound at the left tip is different, something inside the rear muffler is causing it.

 

my Z still has stock exhaust system. Im not even sure what to look for.

 

Maybe some of the internal baffling came loose??

 

Flux capacitor?

wtf^^^ lol sounds like ur Z is getting a haircut

im far from a expert but it just sounds like somethings loose and vibrating. Did you touch around to see if the noise goes away??

 

I can't view that at work, but have you checked to see if all of the exhaust mounts are intact?

 

Just came back from the brake and muffler shop. Technician told me that the noise if comming from inside the muffler, that there may be fragments in there. He said that I'm going to need a new muffler exhaust and Labor will be around $200.
