I heard a rattling noise coming from under the hood and I knew it had something to do with the exhaust... popped the hood and put my hand down by the flex pipe and I felt a big gush of air coming out from here



I've also got a video, I'll post it as soon as it uploads on youtube but for now thats what I'm coming up with...

has anyone else had this problem, or had to get this fixed? I'm also wondering how much did it cost you to get it fixed?

 

if its the flex pipe u have to replace it. But are u sure it just isnt the gasket??

 

if its the flex pipe, its goes with the cathalyc converter. they will change everything for free. changed mine twice already, 60 000 kms, also verify your firewall. mine is making some noise once in a while

 

YellowRocketSS - I'd hope its just the gasket but, I'm pretty sure its not, just the gasket...

h0l0caust - nothing is free for me anymore... my warranty is over

video of it ^^

 

just find a used flex pipe and get it welded on. same thing happened to mine...seems to be common with cobalts

 

took it to a GM dealership and its getting fixed tonight... found out that its covered under an emissions warranty (up to 80,000 miles) so if anyone else ends up having this problem take yours to the dealership and ask them about the emissions warranty
thanks everyone for the input

 

i have the same exact problem also i have a catback exhaust and i really dont feel like argueing with them do you think ill have a problem with the dealers. on my comments for the dealer i wrote never touched from the cat up and i also stated that i never touched the downpipe.
