  • Q: WRX STI 2018 LIMITED  Mark2 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.
    • 0 of 0 people found the following answer helpful

      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   Saxb63974 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.
  • Q: Difference between the 2014 and 2015+ WRX  BU24U5 months ago

    I have the R400 for my 2014 WRX I'm trying to sell to a friend of mine, but they have the 2016 WRX. I looked at the pictures for both years for the catback and couldn't find any differences. Could you tell me if it'll work, or not at all?

      A:  We are not able to confirm fitment but the chances of it fitting are slim to none.

  • Q: 2018 WRX Base model  donottouch7 months ago

    I have a 2018 WRX base model, do I need to buy anything else to make cat-back system fit?

      A:  You will need the following links for installation with the OEM downpipe. https://www.rallysportdirect.com/part/exhaust-gaskets-and-hardware/sub-44022aa123-subaru-oem-donut-gasket https://www.rallysportdirect.com/part/exhaust-gaskets-and-hardware/grm-077046-grimmspeed-oem-downpipe-to-3in-cat-back-adapter

      A:  Info given was incorrect, you dont need the 3inch adaptor to fit the oem down pipe to the catback system. You also dont use the oem doughnut gasket, a flat gasket is provided in place of the doughnut gasket. Shipment came in last week and did the install a few days after. After inspection of the stock system, and comparing it to the new system, it is all direct fit bolt on. This review applies to the 2018 wrx base model. Not the STI model.

  • Q: Exhaust Sound Comparison to 2017 Stock Subaru STi Exhaust  ScoobySTi8 months ago

    How does the sound of this exhaust compare to the 2017 Subaru STi stock exhaust? I saw some comments about folks stating that this exhaust is "quiet". I know there are videos out there, but it's hard to gauge based on the ones I've seen.
  • Q: OEM to 3inch adapter  Matthew W9 months ago

    I have 2018 wrx premium and its been brought to my attention that if i purchase this exhaust i will need some special adapters? Where can I purchase a OEM to 3inch adapter and how much is that part?
    • 0 of 0 people found the following answer helpful

      A:  If you are installing this exhaust to the stock downpipe, you would need a Stock Downpipe to 3" Catback adapter. Grimmspeed does make one, which you can find by searching Part # GRM 077046

  • Q: Invidia Gemini R400  Ray1 year ago

    I recently bought a 2018 Wrx limited and want to upgrade exhaust to the Gemini R400 with titanium tips to improve looks and definitely sound. My question is do I need to buy anything else besides the kit if I am keeping the stock down pipe? Also will I have to tune the car. Right now it is 100% stock, and I don't own a tuner. Thanks in advance.
    • 0 of 0 people found the following answer helpful

      A:  You will not need to tune for just the catback. You will need a stock downpipe to 3 inch catback adapter however as well as a new donut gasket.

  • Q: R400  Wes1 year ago

    Does this exhaust drone at cruising speeds (i.e.. on the freeway, running around 75mph)? How does it compare to the Greedy Supreme SP for a VA STI?
    • 0 of 0 people found the following answer helpful

      A:  Sound is something that is EXTREMELY hard to imagine when talking over text. Everyone has a different idea of what drone sounds like but for the most part not this should not have any drone. For comparisons I recommend going to YouTube and comparing other customers sound clips.

  • Q: Adaptor  eson3989513951 year ago

    Which Adaptor would you recommend we purchase to mate the downpipe to the exhaust?
    • 0 of 0 people found the following answer helpful

      A:  Depending on the downpipe you could do Invidia, Grimmspeed or Mishimoto. All those brands would be great.

    Was there any changes from the 2017 to 2018 model in terms of exhaust that may affect fitment? I just bought a 2018 wrx and would be interested in purchasing this exhaust. Thank you!
  • Q: Retune  ckym1 year ago

    I'm already running Q300 and dowpipe, with protune. If i change mine to this (catback only), does it require a retune?
  • Q: Invidious Gemini Cat Back  theicewall250452 years ago

    How does this exhaust measure in the decibel department. Invidious now makes several exhaust options. Many say the Q300 is no louder than stock. Is this louder or quieter than the N1 and does it drone more or less? Does it utilize standard or long length hangers.
    • 0 of 0 people found the following answer helpful

      A:  This exhaust is supposed to be the choice if the N1 is too loud, but you want something more aggressive than the Q300. Factory hangers should be fine for this exhaust, if you notice it sits really close to your bumper extended are recommended.
