My car started making a clinking noise like keys jangling ro something...only when im accelerating..sounds like its coming from the drivers side front wheel well. i could be wrong though. i cant find anything. any ideas?

thanks

 

Does the clinking sound increase per revolution?

 

Hmm, if it sounds like it is coming right below you it could be the cat failing and coming apart from the inside.

 

no it doesnt really increase, maybe the cat..good thing im getting a hi flow put on this weekend anyway..well see if it goes away

 

Have you noticed if it makes that sound at a certain rev. Have someone rev the engine while you look under the car. That might help you find the prob.

 

if its at around 3500rpm's its probably the heatshield on the cat, mine did it and i've heard a lot of people complain about it.

 

At what rpm? My gsr is making the same kind of noise, a very tight rattle that is hard to hear unless i'm surrounding by two walls. I can only hear it between 2000-2600 rpm......sounds like the cat but I can't be sure....

 

i have a 97 GSR and something on the exhaust rattles at 3500 i thought it sounded like the cat. How did you fix yours?

 

Mine does it also. right at 3500 then at about 4000 it stops.

 

its most likely the heat shield for the cat...take it off. problem solved. oh yea,watch out for small flames coming out though besides you and your passengers feet. (JOKE )

The 3500rpm rattle is the A-pipe/downpipe in most cases. Sometimes it can be a heat shield but I removed all of mine to no avail. I just got mine fixed last week, a couple holes in each side of the intermediate pipes there and a little weld and problem solved. I know a guy that just got his A-pipe replaced under warranty. If yours is a 2000 then by all means have a dealer look at it.

 

I had this problem before it was my heat sheild on my cat i removed it and still that damn noise but their are many heat sheilds down there so it will always happen!

 

This is most likely the case. Heat shields don't just bend on their own. GSR's have a tendancy in the stock exhaust manifold/downpipe to start rattling after a couple years...

 

I've got a 96 gsr, and everytime (3 times) I had a funny noise at around 3500 rpm it's been a heat shield, I would take it to midas and if it's a heat shield they'll usually remove it for free. I would look at that option first because it's the simplest, it could be something else but at least that way you'll know.

 

if its the noise that everyone else is talking about it is the a-pipe. integras have a bad tendency to do this. my friend, the same one patrick is talking about, got his replaced for free and its fixed. good luck with the problem if thats not the same noise.

 

PLease explain your solution further. Drill holes in each side of intermediate pipes and weld holes shut? I was told by dealer that there is an inner an outer pipe and when the two come in contact they rattle. Is this true and if so then the weld is to keep them stationary?

Seems like an easy fix. Any replies very welcome.

 

You are right, the inner pipe comes loose and hits the outer pipe at a certain RPM (certain resonance frequency). The shop took their plasma cutter and made a 1/2" diameter hole in the side of both intermediate pipes. Then they stuck the welder in the hole and shot some weld in there to brace the inner pipe against the outer pipe. Quick fix and they only charged me $20.

 

Typical PEICE of TRASH

 

I remember when I got a High Flow cat after like 30 miles It started clinking around. The heatshield came loose on one side and made this cow bell sound as I accelerated and slowed down.

I would start by checking your Heatshields. If your cat goes bad then you will have a reason for upgrading to a high flow cat. GL

Another solution is to get new headers and a cat.

mine starts to rattle like crazy when it is cold around 2400 rpm's and about 3000 rpm's it stops?? i think it is my cat because i rev'd up my car and stuck my head out my door and the noise seemes like it was coming from the cat. so now that i read this thread i will try to remove the shield. is it hard to remove? is it just a piece of metal on the underside of the cat?

 

It is mostly likely all you guys are experiencing is the A-pipe... the problem is caused by one pipe inside another pipe that has vibrated loose and moved and now vibrates against the other you can have it fixed at a muffler shop I think its around 30-40$, or find someone that is selling an exh. manifold with A-pipe that just put a header on thier car (what I did cost $25), or just an A-pipe since thats all you need, or buy a header (what I would of done if I wasnt going turbo soon)..
