so im 100% stock & my car has about 55,xxx miles on it & I've been hearing a weird sort of zinging sound coming out of the exhaust while I'm in cycling through 1st, 2nd & 3rd & when i rev it. I've just been wondering if thats normal or if i have a possible exhaust leak or whatever it is because its be irritating me. any help or info would be greatly appreciated!

 

any sound clips?

 

@turbosmart4 ill try to get a sound clip tomorrow afternoon & post it on here i don't know whether I'm hearing **** or not but i know for damn sure it doesn't sound right.

 

ok, cuz it might be your down pipe, post the vid and ill see if it sounded like mine

 

do you by any chance have a sound clip just so i could compare the sounds.

 

never thought of recording it... i thought is was the SC at first cuz sounded like "marbles in the can" but it was a blown cat making the rattling

 

Thats the sound of your car wishing it had a ZZP midlength header, catted dp and full 2.5" exhaust.

 

ok so i took it too the dealer cause i got so irritated with the noise & they call me back saying that the trans area is making a noise & they said its probably the clutch but i doubt it cause it works perfectly fine, or they said its the muffler....? & they also said both aren't covered in the warranty but last time i read mine it didn't say anything about a muffler not being covered. but idk how a muffler could make a rattling sound when I'm hearing it come from the engine.

 

**** gm, go to an exhaust shop and jack ur car up. most likely its the flex on your downpipe is leaking. is it kind of a pftpftpftpftpfptfptpfpt noise as u go along? if so most likely ur dp. which is covered by gm.

 

@riceburner it does that sometimes does the flex pipe have springs on it if so, mines a lil bent in so that could possibly be it then....imma give them a piece of my mind on monday haha & yes it does make it when I'm going along & gets loud w/ hard acceleration,

 

^ that's definitely your flex pipe. Especially if it's louder under acceleration. Just buy a zzp downpipe, or get header/downpipe combo. Not much more expensive than just repairing it

 

@owen s my cars still under warranty so if anything id go get a gmpp dp

 

Gm don't make a gmpp downpipe....?

 

^lol idk i was just saying cause my cars under warranty & im not tryna void it haha

 

So i did some research & basically im more than sure i have a blown cat

 

u probabably broke your flex pipe, i remember mine sounded like the supercharger was going bad (marbles in the can sound) but it was my blown cat lol it will also sound like your redlining at lower RPMS

 

^ yeah mine is making that exact same sound so its possibly my cat then & the flex pipe is a little bent on the springs but not that much just a little indention on it

 

Dont forget the heat shields. They suck. I had mine tacked up to keep any buzz away from my exhuast.

 

take it to the dealership ,and they will replace it for free man

thats if its not the SC coupler lol

 

^its at the dealer already & they're tryna say its coming out of my muffler & when i heard the message i was like really? i told the guy that i heard it coming from the middle of the car then traveling through the exhaust i swear i just wonder about people sometimes haha

 

hmmm it depends on hoe good the mechanic is lol

 

these guys at chevy dealer took a coupleof hours but got it right the first time

 

i guess over here in california they're just terrible haha

 

they probably are idk lol here in texas mechanics are really good , well the ones ive known... my personal mechanic is pretty bad ass.. charged me 135 for one caliper replacement and coolant flush plus t-stat replacement(parts included) when chevy wanted to take 140 away from me for flush only lol

 

damn your lucky i have no mechanic haha the only mechanic i can let touch my car is by my dads job since they're hella cool with them but dude thought my timing was off since it was making that noise so i won't really trust that fool with my car haha
