I started noticing this annoying rasp type sound coming from my stock exhaust. Anyone know what it is? Its really annoying during acceleration.





Here is another video to compare the sound.

 

i hear that alot from aftermarked like hk i really dont know what it is. i dont think it is a leak but it could be anything. sorry i cant help more but a free bump.

 

did you buy your car used or anything.. maybe the previous owner messed with the exhaust

 

Just buy a new cat-back exhaust system and call it a day! That's what i would do

Besides that, is your whole exhaust and ur cats stock? Cause I seen people that change their cats but keep their stock exhaust that get alot of rasps

 

sounds like either one of your cats is blown, or, more likely, you have an exhaust leak. check out all exhaust gaskets.

 

Not sure what that is, when did it start?

 

exhaust was fine until 2 days ago when i noticed it. There are some rough roads around my college campus so im guessing that might have knocked something loose maybe. Exhaust system is stock. No aftermarket cats or anything.

 

anyone else have an idea of what could be the problem?

 

i used to have same problem when they took out muffler for toe bolt on it was a loose bolt on the heatsheild thingy behind the muffler jack up the car get underneath the muffler and have someone press the gas and find out where the noise is coming from.

 

damn that noise is ****in annoying its something loose and just vibrating

 

yea i will check for leaks and see if anything is loose first. Thanks guys.

 

Check the air scoop thing on the front of the muffler. Mine was making noise like a rattle/rasp noise so I just took it off.

 

I put the car on a ramp and noticed that the sound was coming from inside the muffler. Does this mean the muffler is bad?
