Aftermarket exhaust going bad on my 07 SS.
 

Dealer didnt notify me that my 07 SS i purchased in Dec had a aftermarket exhaust, its starting to go bad and isnt covered under the 3000$ warranty i purchased along with it. Not on good terms with the dealer i purchased from. Ive been taking into my local GM for service. Just pay the 100$ detuctable. I purchased it an hour away.

Stealerships suck. Whats going bad on the exhaust? Time for an upgrade maybe?

Dealer should not be liable for covering aftermarket parts on a vehicle warranty.
Dealer should not need to tell you what an aftermarket exhaust looks or sounds like.
You were aware that the car had an aftermarket exhaust when you bought it.
Not trying to be a dick, but the dealer is right on this one.

I have learned that unless you get a GM extended warrenty the extended warrenty Companys are screwie

I am not sure GM even offers anextended warrenty program any more


I brought an extended warrenty on my 08 Malibu from EASYCARE via the delear. The delaer's hands are really tied when it come to the warrenty. So not really the Deler's fault but the extended warrenty company.

And true after market parts would not be covered by anyone dealer or warrenty company

Feel for ya but that is just the way it works

I second this

Your not being a dick, its just that you didnt get the whole story, i didnt know there was an aftermarket (Magnaflow) exhaust on the car when i purchased it, nor did they disclose it to me. But its cool, the gorgeous sales lady who sold me the car assured me im going to be taken car of. You guys are quick to jump to conclusions. :nono:

Thats true guys, some people didnt know there exhaust was different till they heard it against other montes (like myself). Sometimes people arnt as familiar with cars. I can tell aftermarket exhaust 100% of the time now, but it was a different story a year ago.

What's wrong with the exhaust? If it's leaking, any exhaust shop could probably fix it for cheap. Or just get some of that fiberglass crap and patch it yourself.

Okay...i assumed there something going on with the exhaust because it was getting louder, because i have GMPP i figured i would hit em up for a new exhaust. Thats when i found out it was a aftermarket and not covered under the warranty, this is my local gm dealer, i purchased the car an hour away. So, GM service guy tells me it shouldnt have been sold to me with that exhaust because its a Optimum Used car blah blah blah. Basically stirring the pot IMO. He says those exhausts cause wear on the valvetrains due to the increased back pressure thats why there a chance any problems with powertrain will be blamed on the aftermarket exhaust and ill void the warranty, but my sales lady told me they will honour a new exhaust when and if i need one. So its all good. And i dont believe the back pressure story...

yea I'm not believing that back pressure story either. Yea the engine needs a certain amount of back pressure to be really effective. But in all honesty an after market exhaust is going to flow better then the stock exhaust will which will decrease back pressure. Someone correct me if I'm wrong but the more you decrease back pressure the more HP you get the more back pressure the more torque you get (however minimal it may be). But it shouldn't cause any issue other then that at least to my knowledge

I disagree and then agree.
This is MY feelings on the topic, by no means the cold hard fact: I feel, I the dealer is presenting the warranty plan (the buyer did not seek it on their own), then I feel they have an obligation to their customer to ensure that the customer is either getting full benefit of the plan OR is made aware of issues (such as items not covered with the car in the condition the customer is buying it in).
Sadly, as stated, not everyone is going to know that the car has aftermarket parts. And especially if this is a dealership that plays the "certified used car" bit (giving customers the warm and fuzzies the car was completely inspected), again, my personal feelings are the dealership has skin in this game and I would do my best to hold their feet to the fire to either make things right or for mis-representing options to me.
Again, my feelings towards the matter based on the information I am reading in this thread.

Are you saying the "aftermarket exhaust" is a GMPP exhaust? If so, sure, it's NOT original equipment, BUT, it is an exhaust GM markets towards these cars!! Considering it's a GM branded exhaust, I really think it's silly the shop even mentioned damage to the drive train. :rolleyes:

I hope things pan out to a resolution you are happy with. But if it is truly not a covered item, you may be in a position to compromise with the dealer. But as I mentioned, if that exhaust was on the car when they sold you the car and offered this warranty, then they have some skin in this game.

Warrenty
 

Yes you can buy G M warrenty for your car, its this finding the right dealer that will deal with you on this. I have G M protection plan-Major Guard. $100 ded. and cover till 2-28-16 paid $1800 for the plan. Its a low mileage plan cause i am only putting on about 7500 miles a year on the car.

More proof that dealers in general, do not know much about cars. They tell you anything you want to hear just to get you to sign that contract.

And the mechanic - Umm yeah, the backpressure causes wear on the valvetrain...what?

The Magnaflow aftermarket exhaust system for the 2007 Monte Carlo SS is 100% Stainless Steel, and will not "go bad."

Good job on being persistent with the dealer and making them own the warranty. Looks like everything turned out just fine...:)
