Another exhaust jingle thread..
Did a search and read all the threads and TSB about it. It seems like I have the exact problem described in the TSB.. when coasting in gear or downshifting, you can hear the metallic rattle or jingle.
My car is a 2k3 w/ 27k miles. I just got it and it's a GM certified used vehicle which means it's supposedly got a 3k mile GM-backed warranty. I took it back to the dealer and they said warranty doesnt cover it because it's not necessarily a failure.
That kinda pissed me off so Im thinking of taking it to another dealer and see if they'll fix under warranty or maybe ill just pay for the repairs..
Then I was thinking since the issue seems to be the h-pipe, maybe I should just buy this and have it installed.. http://www.corvettegarage.com/produc...-corvette.html
What do you guys think?

My 02 makes music as well.. I got my dealership to say they are going to fix it but they want it for several days and to outsource the welding to another shop... obviously I said NO... I'm just going to live with it until I swap out the H-Pipe myself.... good luck with yours though.

I have made a few posts concerning the "Jingles". I have tried all of the tricks i have read here to remedy the problem yet, it still makes noise. I did however find another possible culprit. The oxygen sensor lines going into the exhaust pipe have metal caps on them, which strangely enough, rattle under heavy revs. I wrapped them with some of that fire proof header wrapping & secured it with a couple of hose clamps. That solved most of the noise, but some annoying jingles can still be heard. I had stated earlier in one of my posts that it is a common occurrence in the stock exhaust system, mosty due to the internal turbulence of the gases flowing through the system. The only other option i can think of, is replacing the H-pipe. You could also have your cats gutted, but depending on your states regulations, you may have trouble passing your yearly smog exam.
