2010 SS exhaust rattle/baffle - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

mrWizard · 02-21-2013, 06:59 AM

I just hit 19000 miles on my 2010 ss and started to hear a rattle noise coming from the exhaust. I have read around and saw that this could be from exhaust control valves not closing or opening properly or there is an issue with the mufflers and they should be replaced.

The rattle is around 1100-1200 RPM, stops when i get past there. Also, seems to get louder as I drive longer. It can be quite loud and can be heard over the radio at times, very annoying.

So I'm wondering:

1. Is a fuse pull for exhaust control valves even possible for my car (built in 2009)?
2. Will a dealer be able to identify this problem and replace/fix the issue?
3. If it isn't an issue with the exhaust, what else could it be?

Thanks in advance for the feed back.

I had the exact issue on my 2013 (right around 1100-1220 in 2nd), see the below thread:

Yes, after the reprogram the rattle went away. I forgot and never updated the thread but the reprogram did fix the issue, not the clip.

As far as I know there isn't exhaust control valves in the 2010. Most people with early models and exhaust rattling, including my car, found that something had broke loose inside one or both mufflers. If you thump each with a rubber mallet you should hear the rattle. Dealership has replaced them for others but some have had the replacements eventually do the same thing. For this reason I went aftermarket instead.

Yeah that's what I figure would happen. I think I'm just gonna go with the muffler delete.

Dealer said it was the drivers side muffler. Something is rattling and they are going to replace everything after the resonators. Now I just wait 2 weeks for parts

At least you'll know right away what is wrong, when the new set starts rattling.

They should replace the cat-back. Had the same issue. Dealer replaced my whole cat-back under warranty. They claim that the baffles in the resonator blew into the muffler.. IDK how true that is.. All I know is that my annoying rattle at idle and at 1200-1500 RPMs is gone!

Oh, and I was told by my dealership that they had to replace the cat-back as GM designed it as one piece. They told me that they could not just replace the mufflers.

Hope this bit of info helps.. Best of luck!
