Great quality, no CEL

Awesome J-pipe

Honestly, you can run this post-greenspeed. No CEL, turbo spools, and significant gains! Totally recommend this J-pipe. High quality GESI cat as well. I think this one and Grimmspeed are the only ones on the market with the cat in the 'proper' place!


This thing really wakes up the car,

like turbo spools? check.
like rumble? check.
no CEL? check.

Race car vibes

I paired this with the extreme tbe w/o a resonater and this shit is loud. I love it. Gives a mean throaty sound @ wot but perfectly comfortable as a daily set up

Great pipe!

Got this since Cobb's were discontinued and am glad I did. This is every bit as good as the cobb version. The cat is GESI and extremely nice. Welds were perfect. Would definitely recommend.



Ask a Question
  • I’ve seen that this downpipe MAY NOT fit on a cvt has anyone even tried I got the ETS extreme catback will be pointless if I go another route.

    Unfortunately the routing of our J-pipe does not fit vehicles equipped with CVT.

  • Do I need an adapter for this jpipe to stock midpipe/ypipe?

    We include a series of gaskets that make up an adapter when using our catback with a stock downpipe/jpipe or vice versa. The order of these gaskets is as follows in the 3" downpipe to Stock Catback configuration: 

    Midpipe -> 2.5" Graphite Gasket -> Adapter Sandwich Plate -> 3" 2-bolt Gasket -> Downpipe

    You can also use an adapter if you would prefer to keep the donut connection, but it is not required to install the part.

  • What do I do with the factory ground strap? Where can I relocate it? Thanks

    At this time we don't have a provision for the ground strap built in to our downpipe, you'll want to utilize the mounting point that is accessible on the bottom of the engine block if you are intending on keeping the ground attached.

  • Can you guarantee no check engine light with this downpipe? I definitely do not want to spend over a grand for a pipe that will only lead to a check engine light and possibly other issues.

    This part REQUIRES a pro-tune in order to guarantee that there will not be a CEL for catalyst efficiency, a tuner can disable this code. If you are using an off the shelf tune there is still a chance that it will throw a code, the Direct Injected cars are a little more finicky even when using the GESI cats.

  • 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!

  • 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.
