  • Q: Invidia R400 Catback Exhaust   21WRXSTI2 years ago

    Will this fit a 2021 WRX STI? Your site says nothing is available for 2021. Also, when will you be getting more in stock.
    • 1 of 1 people found the following answer helpful

      A:  This will fit the 2021 models, I don't have a concrete date on when these will be in stock on our shelves. When they do arrive, they are immediately sent out for backorders.

    Hi, I have a 2015 sti. Just wondering, what would be the exact needed gasket and does the stock gasket fits? Because i just bought a second hand r400 so probably i need a new gaskets.

      A:  It's always strongly encouraged you replace the gaskets with exhaust. You will need 3 inch gaskets for the downpipe and midpipe connections, use GRM022001, and 2.5" for the muffler connections, use GRM020031.

  • Q: Invidia r400 2020 wrx sti  2020 sti3 years ago

    I'm not sure if this has been asked for the 2020 sti, but can I install this catback alone with the rest of the car stock, or do I need the adapter? The reason I ask is because, I have heard of the tips sticking fairly far out when the adapter is installed as well. Thanks in advance
    • 0 of 0 people found the following answer helpful

      A:  You'll still want to use the adapter (GRM077046) with the 2020 models if you're installing with a stock downpipe.

  • Q: TUNE  salty_lays3 years ago

    I have a stock 2019 STI, will I need to tune / adjust my Airfuel ratio with this exhaust. I do not have an accessport and plan not to buy one. Also will this bolt up directly to the stock downpipe?
    • 0 of 0 people found the following answer helpful

      A:  A tune will not be required for a catback on your STI. This will require an adapter, such as GRM077046 to bolt up to your stock downpipe.

    I know it’s not a huge gain but I was just curious as to how much HP and Torque would this add to my stock 2019 sti?
    • 0 of 0 people found the following answer helpful

      A:  Invidia does not offer a horsepower rating on this. Catback gains tend to be fairly mild, expect 5-8 hp/tq or so.
