    Flat 4 Noise 5 days ago

    The R400 is a great exhaust that falls somewhere in the middle of pack as far as sound levels. It produces a significantly deeper and more aggressive note that is a big change from stock. There is some mild drone at the low end but it is not head-splitting. The in-cabin noise can be easily controlled with the throttle. I was also in the market for the AWE touring, but the R400 was on sale randomly and came with a $50 gift card. I used the card to buy an upgraded shifter bushings combo. Car is a lot more fun to drive now.

    Bought and installed this on my 2016 WRX. The hardest part of the install was 50% toss up between getting off the old axleback (new england seized bolts) and getting the new axleback pieces into the hangers (didn't have the grease my bad) but besides that couple jack stands and an impact and you'll be done in a hour or two. Sounds great and causes a little drone on the highway but nothing unbearable. Another great Invidia exhaust.

    QUESTIONS & ANSWERS

    • Q: Invidia R400 Catback Exhaust   21WRXSTI1 year 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.

    • Q: Gemini R400 Gasket  TurboBrunei1 year ago

      Hi RSD, I have a non USDM Subaru Sti 2.5, year 2021 with right hand drive. I am planning to buy the R400 exhaust from you connecting it to OEM downpipe. What gasket I need to buy for this? Thank you, Vincent
      • 0 of 0 people found the following answer helpful

        A:  I don't think this would work for your vehicle, these are only confirmed for USDM models.
