    Fit and worked great. However, I only received one set of washers in the package. I had some on hand so it was no issue but the QC should be better for such a reputable brand.

    I used this adapter for my invidia Q300 single exit exhaust. It's high quality and fitment was perfect with zero issues with the install. Grimmspeed always comes through with quality parts.

    Sharp edge where donut gasket sits 7 months ago

    This looks like a high quality part, but the adapter I received has a sharp edge where the donut gasket sits. I decided to not install this since it will cut into the gasket. So far, it seems like my Remark midpipe is sealing just fine with the gaskets Remark provided.

        A:  A gasket is included, you would need an adapter to go from a stock 2.5" downpipe to a 3" cat back.

    • Q: Grimspeed catback adapter  Josh3 years ago

      Hello, I'm planning on buying the Invidia R400 Gemini Single Layer Quad SS Tip Cat Back Exhaust Subaru WRX / STI 2015-2020 and Invidia Catless Downpipe / J-Pipe Subaru WRX 2015-2020 6MT. Do I need the adapter since it wont be a stock j pipe anymore?
    • Q: Looking to buy this with the Invidia R400 - 2019 WRX  alamsas3 years ago

      Just wanted to confirm how many gaskets come with this product? I'm guessing the tapered side (female?) is where the oem donut gasket sits in between the adapter and the stock DP? The other side of the gasket is for the midpipe of the exhaust? If there's 2, I'm not sure what the other gasket is for. Wouldn't the invidia exhaust come with a midpipe to dp gasket as well? I'm guessing that goes in between the adapter and the midpipe? Thanks,

        A:  This will come with 1 gasket, but you are correct in that the R400 will come with this gasket already, but Grimmspeed includes it just incase you don't have one. Hope this helps. Thanks!

    • Q: Gap between stock DP and Tomei  SMsubaru3 years ago

      when bolting up the tomei with the adapter and donut gasket to stock DP there is a gap between the two pipes. Is this just supposed to press against the donut gasket and be sealed? Ive got it torqued down pretty tight and doesnt appear to be leaking but it just looked weird to me
