Technical Service Bulletin (TSB) re exhaust metallic vibration
 
I took my camaro in to be serviced at the dealer for a dent (completely gone now :D) and a vibrational noise when I was in low RPM's of any gear. The mechanic said he couldn't hear it but I insisted it was there. So the mechanic did some research and found a Technical Service Bulletin (TSB) that described exactly what I said. It turned out the baffles in the exhaust separate and vibrate creating a tinny noise. So now my exhaust is being replaced from the catalytic converter back and its all under warranty. Just wanted to post this in case anyone else had the same problem and didn't know what the hell it was.

Thanks for the heads-up.

I knew thats what it is.I took mine in for the same thing and the stupid SERVICE MANAGER tried to tell me it was gear lash sound traveling through the drive train. Uuuh yyeeaa right. I told them it was a harmonic vibration coming from the passeger rear side. I will be taking my car to another dealer on the 17th.

Do you happen to know what the bulletin number is?

Supermans 05-08-2010 06:33 PM

Send me a PM with the bulletin number. Thanks

esperman 05-08-2010 11:36 PM

glad I ripped off the stock exhaust:)

Me too.
I have noticed a buzzing sound that tends to resonate at 3000 RPMs, with or without the gear or clutch engaged. Seems to be coming from the passenger side and I suspected the exhaust.

Good to know.

exhaust metallic vibration
 
Thanks, I have the same problem and I'm also in Baltimore. Where did you take your car to have the problem corrected? Do you have the TSB number?

Thanks!

had the same problem after they did yet another TSB fix for clicking rear half shafts.. For THAT they added washers to the half shafts near the real wheels.. THEN I started to have that resonance problem..so after MUCH service time they replaced both mufflers.. and.. it STILL gets the noise.. My concern is the other "fix" might just be adding too much directional torque to the half shafts OR the differential.. Who can help with this one cause GM sure can't figure it out

Mine only does it after it heats up. But it doesn't vibrate where I can feel it. It just rattles. DRIVES ME APE SHI*!!!!!!!!!!!!

Stickboy 05-21-2010 01:59 PM

I would like the TSB number also. Thanks

stasha87 05-21-2010 08:49 PM

Has anyone gotten the TSB number yet? I want to get mine fixed!

1fine79 05-21-2010 11:16 PM

Could you PM the TSB number. Thanks.

zonepro77 05-24-2010 09:14 AM

I am having the same issue. If anyone has found out what the TSB number is and could let me know, that would be great. Thanks!

What are the odds we could get a credit towards an aftermarket exhaust? lol

any new news on the exhaust issues?? I haven't had a day to take her in to Chevy but my vibration is getting worse and worse- I can pound away at the exhaust and it's as solid as can be. arrrgggh.

noted areas, so far:
1st gear from an idle stop
2nd gear from a slow crawl
3rd gear on a declerated turn; 1,200 rpm range
4th gear at 31/32 mph; 1,200 rpm range
5th gear at 38 mph; 1,200 rpm range
6th gear at 55-58 mph, most prominent at 56 mph; 1,200 rpm range

You took the words right out of my mouth, word for word. Same rpm range too. Just had my SS into the dealer on Wednesday and they said they needed to replace the entire exhaust so I'd have to wait til it got shipped to them (takes a little longer due to oversize package). Just like PQ. Drives me ****ing bat crazy.

You can find TSBs on the NHTSA site for any vehicle. However, I didn't see one for this. Try this url:

it's ridiculous dude- I'm half ashamed to drive it around with this whiney-assed-clank...I've got to purposefully stay above that rpm band & speed to keep it sounding like a Camaro haha...

I am glad that someone is experiencing the same issue @ the same points... everyone's saying to hit the pipes with a rubber mallet to hear the vibration and there's nothing on either side for me...

let me know if the knew system takes care of it!

I wonder if they'd cut you a deal on the GMPP performance exhaust as opposed to putting stock mufflers back on?
