Features & Product Details

RallySport Direct proudly carries a great selection of quality performance upgrades by our friends over at GrimmSpeed.

 

This is the GrimmSpeed 3-Inch Catted J-Pipe for those of you looking for a great way to improve the power, performance, and the sound of your vehicle. GrimmSpeed designed this J-pipe with smooth bends along with an increase in the piping diameter to remove any turbulence in the flow path of the exhaust. This reduces spool time and improves the turbo and throttle response while allowing the turbocharger to exhale exhaust gases quicker and more efficiently. 

 

 

 

DETAILS:

  • Super durable stainless steel construction
  • This is a one-piece tube with Grimmspeed’s patented turbo flange design
  • The flange is ½” thick while retaining all OEM brackets
  • Provides a smooth 3.5 to 3” transition from the turbine outlet to the rest of the pipe
  • Excellent ground clearance without having to alter suspension components
  • Custom stainless turbo studs to accommodate the Grimmspeed ½” flanges
  • Standard 3rd O2 bung for use of aftermarket sensors
  • 300 Cell Metallic Substrate Catalytic Converter - Provides an excellent balance of reduced restriction of a ‘race cat’ compared to a 200 cell unit

    Great buy 3 years ago

    I love this downpipe. Install was easy, the hardest part was breaking the top right oem bolt on the turbo loose, other than that everything fit like a glove. I recommend this to anyone considering a j-pipe upgrade. The sound and quality is amazing.

    It took me a bit to line up this install and pro-tune but I got it all squared away and it sounds absolutely phenomenal. You hear your turbo spool very clearly but it's nothing too obnoxious. Install was pretty easy. Just WD-40 the turbo studs before you try to take the nuts off. I had no trouble with them stripping or cross threading. AWESOME product Grimmspeed.

    Great quality, bolted right on my 2018 wrx premium. Comes with all the gaskets needed and new studs and nuts for the turbo. Only difficult part was getting the oem one out.

    J-pipe 5 years ago

    The j-pipe is a great piece. Fitment is perfect and the sound is so much more aggressive paired with my Greddy catback. Getting the stock pipe off is by far the toughest obstacle with this install and penetrating oil is a must. I would also recommend the SK semi-deep impact socket because it made the nuts on the studs much more accessible to reach. Overall the j-pipe is a quality piece and it really brings the FA motor to life. Install is a breeze and it includes all necessary gaskets and hardware.

    QUESTIONS & ANSWERS

    • Q: will this fit  NUNU2 years ago

      will this bolt up to the AWE TRACK EDITION EXHAUST?
    • Q: Catalytic converter location  @Ryguysti3 years ago

      In your opinion, is there any reason why some manufacturers place the catalytic converter immediately post turbo while others chose to place it more downsteeam like with this Grimmspeed unit?
      • 0 of 0 people found the following answer helpful

        A:  In theory, a cat placed further back will have less back pressure. That said, having the cat closer to the turbo will heat the catalyst more quickly and allow it to perform more efficiently, so there are benefits to both configurations.

    • Q: Boost  2017 WRX AWE Exhaust3 years ago

      I read on phatbotti tuning that catted downpipes are safer and prevent boost creep. Will this downpipe prevent boost creep?
      • 0 of 0 people found the following answer helpful

        A:  Catless downpipes will only cause boost creep if tuned improperly, but this catted downpipe will be your safest bet when using OTS maps.

    • Q: Fitment  Archangel3 years ago

      Will this bolt strait too the borla s type catback or what will I need for proper fitment
      • 0 of 0 people found the following answer helpful

        A:  The Borla tapers down to a stock 2.5" flange, you'll want to run a 3" downpipe to OEM catback adapter.
