Thread: NPP

    Default NPP

    Could anyone give me the actual GM part number for the NPP mufflers? Not Z06 but the NPP '08 muffler that can be retrofitted to my '07 A6 coupe.
    Thanks in advance,

    I am an invader from the C4 section.

    From what I've read, I believe the NPP exhausts can't be used on a C6 that doesn't already have them. Something to do with the wiring for the cutouts isn't present on the cars without having the NPP installed initially.

    Anyway the search functions on CAC are pretty good so you can try that. You also might want to have a moderator move this over to the regular C6 technical discussion section to get more visibility.

    Good luck from a C4 guy who wants to step up to a C6 but who's daughter is getting married. Now you know where my C6 money is going!
