Rattley sound - seems to be coming from the exhaust
No codes, no noise beyond the normal injector noise from the engine. I've heard this a couple of times and it seems to be more pronounced if I do a quick and light rev of the engine.
Anybody now this sound and do I need to worry about it? Seems to be due to back-pressure to me, but wanted some opinions.
thx.

Re: Rattley sound - seems to be coming from the exhaust (Fastlane)
in 01 there was a rattle in the Ti exhaust, but for 02 they were to have fixed the noise maker and it was to be no more?!?!?!?
I dont think there is a TSB or anything tho......may take it to the dealer and have them reproduce the sound and get a new cat back??!?!?!
hope that helps

It is a harmless noise. Many '02's have it, with no ill effects. I've come to find it endearing. It softens with time. The only cure is to replace the X pipe section with aftermarket. Otherwise, allow it to become part of the character of the car. :cheers:

fast.....if it was built in 3-02, it was actually a late model year 02 car....they start building 02 model year in late June -01 :eek:

I've got a 01 which has the noise even after a new x pipe and B+B Prt exhaust. Thought at first it was the throw out bearing. No ill effects. It sounds like quiet, loose rattle. I can hear it when I'm passing by parked cars with the windows down. I'm kind of use to it now. :crazy:

Hey Brent, assuming you have no other mods to your car, if you install an aftermarket x-pipe (corsa, magnaflow etc.) I'm almost certain the rattling noise will go away.
I have an '02, also made in March, and after switching to the magnaflow x-pipe the "jingle" noise is gone. I know some people say they get used to it but why should we have to.
By the way, GM knows about the problem and have taken their sweet time in fixing it. A friend has an '03Z and it still has it . The C5 registry posted this in their June '02 hot news so maybe the early '03's don't have the fix yet. Don't know about the late '03's or '04's.

HI ON MY 02 COUPE I HAD A RATTLE IN THE EXHAUST. IT TURNED OUT TO BE THE HEAT SHEILD UNDER THE MUFFLER. JUST LOOSEN THE EXHAUST AND YOU CAN GET TO THE SHEILD. FIXED MY RATTLE.

This has been hashed over countless times. What you have is the Z06 exhaust "jingle". It is caused by the design of the stock H-pipe. I fixed mine by removing the stock h-pipe and replacing it with a magnaflow x-pipe.

My "jingle" sounded like rattling chains under the car. I though that's what was being described here. Maybe not?

Like many others I had the marbles in the can rattle/jingle on deceleration. I put up with it for 10 months and finally had enough. Got my x-pipe installed a couple of weeks ago, now I'm a happy camper.
You can get an x-pipe replacement from many of our vendors for between 100-120, the install will cost you between 50-100 at your local muffler shop. The Magnaflow and Corsa replacement x-pipes are 100-150 more.
So for between 150-350 you will have only the pure sound of your V8 exhaust system. :D
Good luck,
John :cheers:
