Does installing cat-back exhaust void GM factory warranty? Do any of the common mods void the factory warranty? GM techs and service managers please advise !!!!!!!!!!!!!!!!!!

Generally speaking any after market mod will void a factory warranty! Unless you pull it off before you take it to the dealer to get repaired. They will try to use the modification against the Vette in question in order to get out of the warranty repair.

Your purchase contract should have the details as well as your warranty contract as to what restrictions you have!

Thanks,Matt

Best to ask your service manager........if he's a decent guy he'll ok certain things. Mine has no problem with longtubes, vortex, hi flows, etc.... I have the GMPP and his attitude is what does that have to do with an alternator...........

As long as it does not affect the part in question for repair, the answer is no.

Some dealers will fight you, my advice take it somewere else.

Interesting- what if you have a Corsa catback and x-pipe that was installed by GM and is licensed to be sold by GM?

That's what I have on my 00....when I asked they didn't say it would...but anything that needed repair and was associated to the mod could be voided...I.E. long tubes heated something up etc...this is why I will wait until my GMPP is up before I do ANYTHING to the car...

When I took my 03 in a few weeks ago for the leaking drivers rear diff seal and leaking clutch master cylinder warranty work someone walked by the car, glanced at my tires up close and then went over and told my service writer I had Nitto track tires on the car. She then said "do you track the car and race it". I said non of your business. Nothing else was said and they did the work, BUT several days later my drivers side cat back practically fell off the car from all the bolt nuts falling off or left off. Coincidental??? I THINK NOT!

They also left one helluva brake fluid mess in the footwell changing the clutch master. They didnt even clean up the mess they made and from a month of leaking on my shoe.

That is not 100% true. The modded part and the failed part have to have some relationship for it not to be covered. Thus if you replace the cat-back and the H-pipe blows up that would not be covered, but if your alternator fails that would be covered.

It does help to have a mod friendly dealer that might overlook some stuff.

your choice of tires has nothing to do with the failing of their parts. I cant believe they even asked you. BTW your response were perfect....

My car has been in there before (I bought it from my brother in law) with major rear end troubles before (they replaced the whole diff 2 times, and fuel pump once) and they asked him how much he raced it also. I dont think it mattered for the warranty work itself, I think they were just curious.

If your dealer gives you a hard tim quote him this law im sure he will change his tune
The Magnusson-Moss Warranty - Federal Trade Commission Improvement Act of 1975 protects consumers from such fradulent activity by new car dealers. Under this Act, aftermarket equipment that improves performance does not void a vehicle manufacturer's orginial warranty, unless the warranty clearly states the addition of aftermarket equipment automatically voids your vehicle's warranty or if it can be proven that the aftermarket device is the direct cause of the failure. The easiest way to check this is to look in your owner's manual under, "what is not covered". Under Magnusson-Moss Act a dealer must prove, not just vocalize, that aftermarket equipment caused the need for repairs before they can deny warranty coverage. If they cannot prove such claim-or offer an explanation- it is your legal right to demand compliance with the warranty. The Federal Trade Commission (202.326.3128) administers the Magnusson-Moss Act and monitors compliance with warranty law.

I am pretty certain my GMPP paperwork states no aftermarket or race parts - claims would\can be voided...I just looked at this earlier as I dropped the car off for a bad HVAC actuator.

That is not 100% true. The modded part and the failed part have to have some relationship for it not to be covered. Thus if you replace the cat-back and the H-pipe blows up that would not be covered, but if your alternator fails that would be covered. This means if your having trouble with lets say your turn signals and the dealer finds that your hazard swith is the reason or if the turn signal wand is to blame they cant say because your engine is modded they will not cover that repair!! They have to clearly prove that your mod caused the failure.

cool! I was avoiding getting LT headers because I didn't want them to blame them for any future repairs...as it might lead them to believe I track the car or something...
