Warranty vs. Aftermarket Parts

I was at the dealer yesterday getting all of the recall work done when the warranty manager noticed that I had an after market can on the exhaust. She asked what else had been done to the bike and I said that I had upgraded the air filter as well. She said that she would have to check and see if they could still do the software portion of the upgrade, "Flat Battery" is what she told me, with the aftermarket parts. I was also informed that running the filter and the can would make the bike run leaner and would most likely void the warranty on the motor if anything happened.

Simply wondering if anyone else has been told this? I have a hard time believing that an air filter and slip-on can would void the warranty on the motor. I have done the same thing to cars and trucks all my life. I am a firm believer in letting the engine breath better.

Any thoughts?

unfortunately this comes up a lot with dealers who are not performance-oriented. by law (magnuson-moss warranty act), a dealer (or manufacturer) can not void your warranty based on aftermarket (non-original) parts alone. they must be able to reasonably prove the failed item was directly caused by the aftermarket part (in other words, if your dash goes bad, they must prove that your slip-on caused the failure). now, if you put a powercommander on a bike and the engine blows a head gasket then the dealer may have grounds for voiding the warranty (but again, only on parts affected by the power commander).

taken from the sema website (www.sema.org):

The Magnuson-Moss Warranty Act may also be helpful. Under this federal law ... the Act says warranty coverage may not be conditioned upon the use of only the vehicle manufacturer's parts unless the parts are provided free of charge. In other words, use of a non-carmaker product should not void your warranty unless it caused the problem.

hope this helps.

Thanks for the information, especially because they made comment on the filter/pipe combination that I bought from you. I personally don't see an issue and I really like the set up that I got from you. Thanks again for the help.
