I would like to know if my new Borla exhaust will affect the warranty of my car. Let-s say a have a problem with my engine, do you think they will say: you have a modified exhaust so Nissan won't pay for the repair.

Anyone had this experience or have an idea?

 

Check the warranty papers. Usually if you do a mod and there is a problem it will not be covered if it is caused by that mod. And I don't think they can blame the tire feathering on your exhaust.

 

My understanding is that the Magnusson/Moss warranty act prevents dealers from not doing warranty work when there is no clear correlation between the mod and the object to be fixed.

And, the burden of proof will rely on the dealer to establish causality of the mod to the problem on the vehicle.

If you can confidently spout a line of two of a legal document (Google search) and threaten to get a lawyer, most service folks will fold.

 

No, as long as it is from the cat back, in 1975 a law was passed about this:

From Borla's site

No, some cars even have BORLA systems as the OEM exhaust. All of our street exhaust products are 50-state emissions legal. Our headers are 50-state legal and C.A.R.B. approved. In fact, it is illegal for a dealer to deny you the OE warranty because you have changed the exhaust system. For more details, contact SEMA, the trade organization of the automotive aftermarket which has been instrumental in protecting such consumer rights, at www.sema.org, and they can refer you to the Magnuson-Moss Warranty Act of 1975
