    Will the Invidia N1 from a 2017 base STI fit my 2018 base WRX ? Thank you

      A:  Yes, this exhaust will work for both 2017 STI models and 2018 WRX. As it's designed for 2015+ WRX and STI models.

  • Q: N1 fitment & Hangers  Reese1 year ago

    Do I need to purchase an adaptor, grimmspeed adaptor, if I wanted to connect my Cobb catted downpipe to the Invidia N1? Also, would the stock hangers make the tips hang to low because I would prefer a high and tight fit.

      A:  An adapter is highly recommended if installing with a downpipe that uses a Donut gasket like the Cobb or OEM. The stock hangers generally work well but a stiffer option like the Kartboy hangers can be used.

  • Q: Hi  James3 years ago

    Is this exhaust 3" all the way to where mid pipe mates to down pipe? Or does it reduce to 2.5"?

      A:  The y-pipe after the midpipe does reduce to a smaller diameter 2.5", but with there being two pipes volume actually increases.

  • Q: N1 vs Q300  seanarcilla4 years ago

    How much louder is the N1 compared to the q300? I've watched multiple videos, but I'm still unsure. I'm also interested in cabin noise (drone and such) for highway cruising for both exhausts compared to stock. Thanks!

      A:  Overall the N1 is a much more aggressive racing exhaust. The q300 is a perfect exhaust for someone who wants a good sound without something that's very loud. The N1 will have a bit more drone, and overall be much louder than the q300.

  • Q: Install onto stock downpipe.  ryanwilson2007061384 years ago

    Is it required to have the OEM downpipe to 3in cat back adapter to install this exhaust on my 2015 wrx, or can it be installed with out the adapter?
    • 0 of 0 people found the following answer helpful

      A:  Some customer will use the adapter, others will simply use the donut gasket. There are multiple ways to install it but the adapter does make it easier.
