I think I'm gonna need a new exhaust... AGAIN

[Rogue Leader]

UPDATE:

My dealer replaced the exhaust today, (in just over an hour!), I haven't picked it back up yet, but hopefully this is the last one.

I think it was around 7k. I am almost 15k now and so far it has not returned.

Update almost 27k and the exhaust is doing it again, but this time its louder and more often, hope to get her to the dealer this weekend.

anyone with headers get their dealer to cover this on warranty?

I have headers and aftermarket exhaust back to the axle but stock mufflers.

mine just started doing this at idle, annoying as he||.

Update confirmed, they are on order now, oh well the dealer can keep getting them and putting them on, since its a daily driver i have the extended warranty, so let them do the work!

FYI, 2nd thread ive posted this on:

I have to share my story here, since all of you have been so helpful in helping me with these issues. But to make a long story short, and i mean starting back from 11/2/10 all the way to 2/25/11, my exhaust system and driveline has been replaced under warranty all relating to the issues discussed in this thread...

I originally took my '10 SS in to my local dealer and told them about two noises that i heard comming from the rear and right front area of my baby. They heard the exhaust noise and decided to order a new system from GM. As for the second noise, they claimed it to be all related...
With the exhaust fixed, i immediately went and had the mufflers chopped off, an awesome choice by the way and highly recommended. However, the squeek comming from the right front of my baby had not gone away and was progressively getting worse. I described it as more noticeable during decelaration, usually at lower rpm's and in all gears. Trying not to make this an essay, i had to take it in to two different dealers, six different, consecutive times in order for the problem to be fixed. The 4th time i picked my baby up, i drove it 3 stop lights up the road, flipped a bitch and drove it right back to them... I did end up with a free '11 Tahoe rental for about 2 weeks though...
So in the end, after replacing the exhaust system and then trying to chicken shit me about "loose baffles" and "noisey aftermarket exhaust hangers" and tightening the "loose" exhaust clamps due to my chopped off mufflers, they came up with ordering me a new driveline... And when i say driveline, the part number they indicated on the invoice was 92246788....SHAFT 5.44. Thats a new exhaust system and a new driveSHAFT all in one years time...

So this wasnt short like i said it was going to be, but i wanted to share this with the rest of you in case your baby starts to make the most annoying sound in the world after you have replaced your exhaust system and/or mufflers and cant figure it what in the crap it is... It just might be something serious...

By the way, my baby runs great now, and im praying to sheeba that this is the last of the problems... Ill keep you posted if not.

Well folks, my last post in this thread was 9/30/10 where I was happy with my second new exhaust.

Now the car has over 24k miles and guess what I noticed this week. The SAME RATTLE SOUND. The new exhaust is doing it too! 5 months the exhaust lasted... 5 MONTHS!

I don't know what to do at this point. I am not getting a new exhaust installed every 5 months till my warranty expires. I also really refuse to lemon law the car as I love it otherwise, but this is just ridiculous.

I hope that my dealer can get GM to agree to some sort of compensation or upgrade to an aftermarket setup. I want to wait a little more till it gets really bad again as I want to make sure my dealer is covered and doesn't have to eat this. They have been more than accommodating and helpful in this and its not their fault that the baffles in the exhaust keep breaking up and making noise.

Anyone have any experience here?

Mine just started doIng this. I hope they don't try and say it's my axle back causing it. I get noise at around 3500 Rpms and when I hit bumps. Idk what to do because if they put a new exhaust on it I'm gonna have to reinstall the axle back again.

I think mine is starting to do this as well, but it seems to be coming from just underneath the passenger seat floorboard...It only happens at high rpms above 3,000. At first, I thought it was a pre-ignition problem, but I've been running nothing but 91 octane through it and I did the fuse pull fix as well...I'm starting to think it's my exhaust system rattling, gonna crawl under it this weekend, then it take to the dealer...frustrating
