    #7 Resonator removal = warranty exposure?

    Used to be at Dealer A with an ’06. Removed the #7 resonator and they loved it.

    Now at Dealer B with a ’10. When I traded in the ’06 the sales guy warned me not to remove it on the new car as it could/would affect the warranty on something expensive, like um…the engine.

    Opinions?

    Under the Magnuson Moss act (more or less) the modification has to contribute to the cause of failure for them to deny warranty. Could they connect the dots from exhaust to engine? IMO yes, if they want to be jerks.

    Yep.

    “The additional noise caused the wheel to come adrift”,

    or

    “the 2 additional bhp liberated by the removal of the resonator overloaded the transmission’.

    Happily on either vehicle the powertrain has been bulletproof, it's other bits that tend to fall off.

    Yeah, unfortunately everything appears to work in their favor. They deny you first and then you have to pony up and fight them back; if they're already telling you no about exhaust affecting the engine, probably best not to fight them as they sound like they'll nit pick.

    It sounds to me as the salesman has too many opinions, meanwhile in every dealership sales is distinctly separate from service and your questions moving forward regarding matters of warranty should be directed at the Service Manager because at the end of the day he is the one with common sense and or the big rubber stamp.

    To me it is all about relationships and Curtis Frontin, the service manager at Jaguar Land Rover of Annapolis is by far one of the best in the business. I make it a point to stop by his office every time I am in the dealership.

    Why not just weld it back in before trading?

    If there is a big warranty expense related to your exhaust, they will probably say the warranty is void.
    I changed the muffler, cat back, on a BMW. Cats went bad and BMW said no warranty. $4,000.00 expense to me. Good thing is I got some better flowing cats. Bad thing, I had to pay.

    By the way, the BMW dealer was great, BMW of North America over ruled the dealer on the warranty.
