*edited*

of course i went back to the shop... and they didnt find anything.. they told me about how rock solid my exhaust system is ... so it must be something else...

as you can hear my system only makes this noise when i let go the gas.... as soon as i step on it the noise goes away..

 

i dont think thats the exhaust

 

sounds like viberation. Its something that is rattling.

Did you check the hinges? Also, what kind is it?

 

hks mufler.. custom piping... what else could it be?

 

belts, bearings...dealer time bro

 

uhh.. edited the link so it.. uhm.. works.

it sounds like something is vibrating against metal.... have you actually looked under the car yourself?

hold the exhaust pipe and start shaking it... see if it's hitting against something.

 

damn man that sounds awful... i feel for you. hope you find out what it is.

 

that sounds like the pipe hitting the bottom of the car when u shift. it happened on my civic before. have a muffler shop look at it and see if they can heat up the pipe and bend it away from where its hitting (if it is hitting something)

 

the problem is: sometimes you can hear it when im parking.. but whenever i go to the muffler shop the car stop making the noise............

even here.. at my home.. i heard the noise.. i lifted the car to see anything and it stopped making the noise

1 i heard the noise.. i jumped out of the car.. ran to the back.. i heard the noise i didnt see anything........

of course the car was lifted up and we didnt see anything what could cause the noise (((


i cant hold the the exhaust because tgis noise comes only when im driving.... what im gonna do is.. im gonna lay down in the trunk.. ask my bro to drive.. im gonna open the hatch and grap the exhaust while hes driving my car to see if it really stops...


TO BE HONEST>. i had a problem almost like this.. noise from the exhaust.. i took my car to the same shop.. the SAME guy fixed my car .. he had to tighten up a bolt... but now he said.. everything looks fine.. the exhaust is rock solid..
my problem was: when i wanted to laucnh in first gear.. and slowly took off my foot of the clutch the exhaust started to shake.. thats when the noise came in... but now.. it doesnt doo the same... i try this:

pull e break then, slowly let go the clutch.. but its just doesnt do it anymore.. so.. i dont know...

 

im goin to get the same exhaust well im goin with the 65mm inlet ti tip one, and im getting custom piping so i will let you know when i get it done, maybe the shop just did a poopy job on the installation of the piping

 

Mine hits one of the crossmembers under the car when it's wet, doesn't sound like that at all. That sounds more like there is something bouncing around inside the pipe, although it sounds a little loud for that.

 

i'm telling you.. to actually grab the exhaust and shake it to try to duplicate the noise...

have you tried that?

i dont care if it makes noise while driving.. you need to troubleshoot and the first thing is to determine if it's rattling against something.

 

Yup, that's how I found out where my exhaust was hitting. Get the car on some jack stands and get under there and just move it around as much as you possibly can.

 

yes we did.. and we didnt hear anything at all...

 

im telling you... that exhaust system is really stiff!!!! it cant move around that much............. but i told you guys.. if i pull the e brake.. then put in first gear and let go the clutch without touching the gas exhaust starts to shake as much as it can.. but no noise!!!!!!!!!!!!!! its WEIRD!

 

From the sound clip, it sounded like it only did it on decel, or atleast it was the most obvious on decel.

 

do you have a intake cold air intake?

 

he has k&n

im almost completely sure its your intake rattling

 

yup sounds like it... Something may of came loose from a mount or something holding the CAI... sounds like my injen when it rattled

 

what??? the noise is coming from the rear........... from the muffler... ( right side)

yeah my intake is moving back and forth but i already wrapped the pipe with ribber.. im doing the home depot lip kit diy.. so i now i have chance to check out my intake.. and no noise from there.. because last month i already wrapped it with rubber...
