    Not sure why they are up side down....
    Overall. A good buy. Installation was fairly easy. The fitment was perfect. You will need the Grimmspeed adapter. I didnt need a new donut gasket. The sound is louder than you expect. It drowns around 2500 - 4500 rpm, as you shift. One you get to cruising speed (60-80mph). Its not bad at all you can talk without a problem. The tips out the back look AMAZING!! I'm glad I got them.

    Sounds as good as it looks 3 months ago
    Hien
    I was a bit skeptical at first. I read some of the reviews and some people were complaining about how loud it was. I installed this and just fell in love with how it looks and sounds. It gives it that deeper rumble and zero drone even when cruising 60-70 mph. I can still have conversations inside the car like normal. I love that I can hear my Cobb intake as well. I expect there to be changes to sound once I install a downpipe as well. Some car enthusiasts will tell you not to expect any performance gains from just a catback but I can definitely feel the difference. Thanks rallysportdirect for getting this out to me so quickly!

    2016 Wrx 5 months ago

    Beautiful exhaust. Very blue in sunlight. Sounds loud only when you want it to. I can come home at night from work in stealth mode by keeping the rpms low, and loud during the day when i want to open it up. All around thrilled with how it sounds/looks.

    Loud But Not Annoyingly So 6 months ago
    Daimyo
    It's definitely noticeable and a bad turner. It sounds great at any speed and rpm however there is a bit of drone at about 2k to 3200rpm for me. I just installed it not too long ago so it should quiet down after a few days.

    2018 wrx base  8 months ago
    donottouch
    Pros Good qaulity catback system from invidia. Easy to install All hardware and gaskets are included. Nice deep and loud tone. Burnt tips look great Cons Has a little highway drone/ not to loud though, but loud enough to forced to turn my music up to get rid of it. Fitment of the mufflers are not exact, one side is too close to the inside of my bumper fender. I had to run on one hanger so it dosnt touch. There were no instructions at all. No pictures nothing at all that i can reference to my specific year. Alot of wrong info given on this site, for my 2018 wrx base model you dont need to purchase a 3in adaptor to connect oem downpipe to the catback. It all bolts on, just use the nuts and bolts provided that came with the system. The exhaust is great but too loud for my liking i should of just gotten the axel back. Rally sport direct is a great site with good prices, shipping came a day ahead schedule.

    • Q: WRX STI 2018 LIMITED  Mark4 months ago

      Do I need an adapter for this? Also what are the gasket sizes? I just recently installed this and one of the gaskets are no good.

        A:  For the adapter, you'll want part number: GRM 077046. The gaskets would be GRM 022001 and GRM 020031 depending on which one is bad.

    • Q: R400 cat back exhaust   Saxb63976 months ago

      I have recently installed a invidia r400 cbe to my 2011 wrx. The exhaust is meant for wrx’s from 11-18. I have read that I’ll need an adapter? So I bought an invidia stock down pipe to 3” cbe but it doesn’t seem like it fits ? But the stock down pipe slides into the cbe and seems like I don’t need an adapter.
