    It works! 3 years ago

    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! 3 years ago

    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

    • Q: Install on a different car  Simeon3 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  chraxter3 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.
