    Installed the exhaust in the drive way in about a hr. Packaged very well, comes with everything you need. Sounds great even with a stock downpipe. I would say it’s equally as loud as my single exit invidia was if not louder. Fitment and quality is A+

    Sounds amazing with the Invidia catless downpipe and Killer B headers. I was disappointed that it was a delivered with a dent in the side of one of the canisters but it still sounds great.

    2014 WRX hatch 3 years ago
    5out of 5stars

    I got this exhaust because my WRX with stock exhaust was so quiet. When I first fired it up I felt like the R400 was too loud, but after a week or so I think it just sounds perfect. At 2k RPMs it has a nice deep rumble that is not too loud. Once you start to get a little higher in the RPMs it gets really loud. I did not dyno before or after and I cant say it feels faster. Went together super easy, had the install done in less than one hour with only hand tools and a floor jack.

    QUESTIONS & ANSWERS

    • Q: R400 vs. Q300 volume?  Justin_sti2 years ago

      I currently have a 2012 sti hatch with the invidia catted downpipe and a Q300 catback with the resonator deleted but still have the huge muffler on it. Would the R400 be louder than what I currently have? Or do you think because my midpipe is non-resonated now it wouldn't be much of a difference.
      • 0 of 0 people found the following answer helpful

        A:  The R400 should still be louder, but with your setup it maybe a good in-between.

    • Q: Install info '14 WRX Hatch   Thomas R3 years ago

      Is the install straight forward? Are there any adjustments i would need to make to hangers or any parts that do not come with the kit that i will need to attach to the remaining stock exhaust?
      • 0 of 0 people found the following answer helpful

        A:  You will need an OEM downpipe to 3" catback adapter and a new donut gasket but nothing else will be required.

    • Q: Additional Hardware Required  Wayne3 years ago

      I have an '08 sti hatch, purchasing a Cobb downpipe and Invidia R400 cat-back. I am buying a new donut gasket and a Grimmspeed adapter for the dp to cb. Will I need to buy additional hardware such as new studs/bolts/nuts or is everything already included?
    • Q: N1 vs r400  narrowbodyenthusiast3 years ago

      Hey RSD, I'm torn between the n1 dual exit and the r400 Gemini. Which has a deeper tone? And which one would be better for a daily driver?
      • 1 of 1 people found the following answer helpful

        A:  Both exhausts will have a pretty deep tone, although the N1 will be slightly deeper. Volume wise for a daily, they'll be fairly similar as well, but the R400 will be slightly quieter. The Q300 would be Invidia's most "daily driver friendly" option.
