Hi Shipmates!!!

I too have the dreaded Exhaust Jingle on my 02 Z. I am looking for responses from those that have had the GM X pipe cure. What are the pros and cons of the fix? Does the cure work? Any change in exhaust note (growl)? Are you happy with the fix? Thanks for your responses, I can't decide whether to have the fix done.

i am also interested hear it too often and want to fix it, what repairs are you refering to to fix this problem??
There is a TSB on the H pipe section of the exhaust. The dealer will cut out that section and replace with an X pipe section to cure the jingle. I have not had it done, but do a search, you will find many threads on it. Installed GHL Magnums and love the sound of the exhaust since.

just went to dealer and got a copy of the TSB, went to parts dept and they do not have the parts, gotta go in on wednesday so they can open a repair order and order the parts, think i'll have them look at the TSB for lifter noise too.

It's not X-pipe, just a different spec H-pipe. They will cut the current H-pipe between the H and the cats, then replace that section with another H with larger holes.

Wah is correct. I had it done a while ago and it works. According to my mechanic the H-Pipe on the replacement is full diameter internally versus the small internal diameter of the original. Externally it looks identical. Get it done. :zboobie:

I have the same problem, too. Would an aftermarket X-pipe cure it?
Yes, but if you are considering upgrading to a complete header exhaust system, might as well do it all at once.

Corsa seems to be the X-pipe of choice. I also have the jingle which best described sounds like a set your girlfriends wrist bangles shaken around a lead pipe. As I'm going to replace the entire exhaust anyway, I live with the jingle for now.

The question becomes which exhaust to replace it with :p

Now that my car has 9,000 miles on it, it is less noticeable... I think.

Maybe the miles at WOT have changed things. :lol:

So is this a 'recall' type 'free' fix, or is it a 'if you want it you'll have to pay for it' fix? Is this limited to '02 models? I don't currently have the noise, but I've got just over 6k on the ODO, hope I don't develop it, and I'd certainly want to get it done while the warranty is still alive.

From my experience, I have only heard of it on 02's.

Hi Sheriff,

The TSB states that it could affect 02-04 models. I just found out today that it will be repaired, free of charge, for those that are still under the 36k mile, 36 month warranty. If you have the extended GMPP warranty in effect, you are SOL, and have to pay out of pocket. The pipe alone is $500 and some change. Then you need to add labor. SO....... if you have it, get it fixed for free under warranty.
