Great sound!

I spent months trying to pick an exhaust system out for the car. I am glad I got the ETS Extreme with resonator. Nice sound with little droning but not bad. Like that the whole system is 3 inch!

Eric Bryant

Paired with the Tomei Xtreme, it’s the best sounding Downpipe I have heard so far!

Chaz Weichey

Paired this downpipe with the extreme catback and fitment was perfect from turbo and brings out the true Subaru sound!

Jonathan Bernal
Catted downpipe

It’s louder than I thought and I love it! Sounds amazing and makes the car sound more aggressive. 10/10

Ive been using the downpipe for about a week or so and i have it paired with a Tomei Extreme Catback. It sounds amazing, on WOT it lets out this nice aggressive roar but as i cruise while on a highway, the drone is very minimal. The moment that i opened the downpipe, the welds looked amazing, it looked and felt like it was built with quality. You do have to run a protune on it as Cobb OTS tunes are only going to allow you to run it but it still leaves a CEL for the O2 sensor. I highly recommend this downpipe

Jeremy Moses

Got my catted jpipe and I’m in love with the welds 😍 clean product going to install soon.



Ask a Question
  • Could this be shipped to California?

    Unfortunately, the only items we can ship to CA at this time are catback exhaust systems, couplers and clothing.

  • Does this work with a stock wrx (mt)and can it just be installed and run without any tuning (knowing your not getting the full benefits of the part)?

    We recommend a tune when swapping out the downpipe. 

  • Will this fit the 2021 wrx?

    Yes! This part is fully compatible with the 2021 WRX, but it will not fit CVT Transmission.

  • Does this fit a 2019 sti

    Unfortunately this only fits the WRX.  We recommend an Invidia downpipe for the STI.  If you need help finding one please send an email to sales@extremeturbosystems.com and we would be happy to help you out!

  • Is this the catted and resonated down pipe pictured?

    The pictured option is with a HFC. You can't run a resonator and a HFC.

  • Will I need an adapter if I have the ETS axle back and mid pipe?

    Nope!  We designed our downpipe to bolt right up to our midpipe.

  • Will it come with the gasket where it meets my ETS extreme catback? Because I have the stock jpipe to ets catback adapter at the moment.

    It will!

  • Will this part fit onto a 2019 CVT wrx?

    Our downpipes don't fit the CVT models unfortunately.

  • Is this part also need tune after install it immediately or I can install it without tune now & maybe in future make tune?

    This part requires a tune.
