    just what I needed 4 months ago
    5out of 5stars

    perfect for mating up my 3 in downpipes with my stock catback on my 05 outback XT. very easy install, nice quality part, what more could you ask for? just make sure you round up a new donut gasket if you haven't replaced the old one in a while.

    It works! 5 years ago
    5out of 5stars

    Bought this because I wanted to re-use the stock exhaust over the winter with my 3" Invidia downpipe, works as designed, doesn't leak at all. Just be sure to buy a donut gasket as one is not provided.

    Great Product! 6 years ago
    5out of 5stars

    I have a catless Invidia downpipe to an SPT catback on my '14 WRX hatchback. I had an exhaust leak where the two joined. I bought this product along with a new OEM exhaust donut, installed it, and it completely fixed the exhaust leak! The car sounds great again! This is a high quality product with all of the hardware that you need to install with the exception of the donut. I highly recommend this product for an aftermarket downpipe to a stock or SPT exhaust

      Will this work with Invidia Downpipe to cobb catback exhaust and do i need anymore gaskets at the bottom for this
      • 0 of 0 people found the following answer helpful

        A:  This will help create a perfect seal. It is highly recommended to buy a new donut gasket as well. GRM020099 or SUB44022AA123

        A:  Yes, this adapter will be the one needed if installing Cobb's downpipe to a 3" catback exhaust.

    • Q: Install on a different car  Simeon5 years ago

      I am looking to possibly install this on my 2006 GTO with 3 in downpipe to 2.5 in cat-back. To confirm that it will fit, what is the distance between the two bolt holes and what is the outside diameter of the pipe on the cat-back side of the adapter? Thank you!
      • 0 of 0 people found the following answer helpful

        A:  Unfortunately we do not have the measurements of the distance between the two flange holes but they are ovalled out to help fitment with multiple sizes.

    • Q: Invidia to SPT  chraxter6 years ago

      Will this product work on an Invidia Downpipe to SPT Catback on a '14 WRX?
      • 0 of 0 people found the following answer helpful

        A:  If the SPT retains the OEM donut gasket, than this will create a great seal. Its not required but is recommended for catbacks that are smaller than 3 inch.
