Just lately, whenever i start my car or just rev it up to 3000 in between it has this werid vibration noise.. i know it because i never heard it b4 and it really sounds annoying, it sounds like its coming from the exhaust inside itself, sound like theres something inside but not really. i dont really know what is wrong but im guessing the exhaust is somewhat loose? i really dont know..

 

i think its probobly the exhaust flex. not too sure about it to unless u provide a sound clip. do u have a aftermaket exhaust?

1. might be the exhaust flex.
2. exhaust hanger.
3. someone sticked something inside. :-p

 

did u run over anything or hit anything

your exhaust pipe could be bent.

 

hmm ill post a sound clip asap!

 

What exhaust do you have? CATS, TP's?

Could be a flange leaking...

he's bone stock

 

I got a same thing on my coupe. It's rattles, almost as something loose in there.

 

Noises.........take it back to the dealership if you have any warrinty left or
if you don't run it by a reliable muffler shop and ask them to check it out.
You've got to have it in the air, running to find the rattle.....like on a hoist.

 

There is a very common problem with CATS and TP's and aftermarket exhaust combinations that make this sound. This is the first I have heard about it on a stock system.

The issue, usually, is that the engine firring order can be hear from about 2400-3600 or so RPM, at different points, as the exhaust is freer flowing, and you can generally hear more sound..even in the pipes themselves.

If this is happening to a stock car, I can only think that the CATS or the factory Y pipe is having an issue at the flex joints...which is also very common.

so bascially ill just take it to the dealership and tell them something is wrong with my exhaust and that there is a different sound being generated then before?

 

For a stock system....that's where I would go...
