Apparently no one here, like with most dealers and mfg's reps, has ever heard of the Magnusen-Moss Warranty Act do 1975!

Here's a link for reference. http://www.dummies.com/how-to/conten...ty-intact.html

In a nutshell this Act makes it illegal for manufacturers or dealers to arbitrarily void your warranty because of an aftermarket or performance part. Here's the key... To void your warranty the manufacture (not the dealer) must prove that the part caused whatever is now wrong with your car. Even then this is on a case by case basis. It is illegal for them to void your warranty simply because they see a performance part of your car.

It's surprising how many dealer and mfg people are unaware of this. Like anything else in life sometimes you will have to fight for what is right.

This has been discussed numerous times. In a nut shell, do you have the financial where with all to take on a major corporation through extended litigation ? I doubt it very much.

ccmano

I'm sure it's been discussed. That doesn't mean anybody knew what they were talking about. Like I said you may have to fight for it. I was a mfg. rep for a major car manufacturer for 30 yrs. If properly escalated through the system and you make enough noise you would be surprised what they will do, I've seen it! They are very squeaky wheel oriented.

In this case if all else fails you still don't have to sue. The Act is under the jurisdiction of the FTC. The next step is to file a complaint with them.

All of this doesn't mean they can't turn you down for a warranty repair. It means they have to prove the part caused the problem. They cannot issue a blanket voiding of your warranty.

This has been worn out on the forum for years. Bottom line is the warranty book details what is or is not covered. When you gamble with your warranty you gamble with your money.

ccmano, I fully understand what you are saying and, I agree. The problem is that most simply don't have the means for a protracted legal fight and GM knows it. At any rate, rarely do the parts cause the issue. It is the ensuing tune that creates the trouble.

calemasters

I agree. The warranty remains in tact, until there is a failure related to the aftermarket modification. When the vehicle comes in with a related failure, and a link is made between the aftermarket modification and the failure, then the warranty can be denied and a partial warranty block can be placed on the VIN.

Ahhh,the famed MM Act. The battle cry for modders the world over. And probably the most misunderstood piece of paper ever written. Somehow, the guys at SEMA latched onto MM to eleviate qualms from perspective clients.

The MM Act was instituted for parts like alternators,batteries,water pumps, etc so we couldn't be held hostage by manufacturers to buy OEM replacement parts to keep our warranties intact.

It was not meant for performance parts like headers,superchargers,gears,etc. I've searched the World Wide Web on several occasions trying to find a case where a performance mod was successfully litigated under the MM Act. Not a single one found to date. And you can be sure someone would have been crowing about it on the web if they had.

Its not the headers that void your warranty...

Its the Tune...

Some dealerships are mod friendly. Need to find one and make a working relationship before something goes wrong.

I had one dealership, where I purchased it, deny PT warranty due to headers (fuel pump evap line was bad). Went to another and no problems at all. Guess who does all my work now.

MikeyTX

I said that too in my post.

If I install headers on my 08 LS3 and do not get a tune what is my estimated net HP gain? Just gauging wether or not its worthwhile because I do not want a tune for warranty purposes as stated in this thread.

You have to tune it or it will throw ck eng lights and codes and won't run right. Also with headers your 02 sensor gets moved.

And it will run real lean
and
go boom

But if he tapes it and it goes viral on UTube with enough clicks .................. o/p's rich .

Thomasmoto

Good point Chip. I left that detail out.

MikeyTX

Headers w/o a tune ?

RED HARDTOP

I ran headers on my 2011 GS
without a tune for five months and over 3000 miles without any codes, lights coming on and no engine going boom. I had it deynoed and made 20 rwhp and 21rwtq with no tune. I put 600 miles on it before taking it to be deynoed. I have since had it tuned and made an additional 11 rwhp and 14 rwtq. I guess I was lucky I had no issues.

RED HARDTOP

Oh, and it was not running lean. AF was. 12.2. .

Real lucky
