2015-2021 Subaru WRX (with 6-Speed Manual Transmission only)

Features:

With the Grimmspeed J Pipe, the devil is truly in the details and the product development team here at GrimmSpeed has taken the time necessary to knock each of those details out of the park. As a result, what you see here is a meticulously engineered J-Pipe with an innovative flange design, single piece construction, excellent ground clearance and fitment with superb quality and craftsmanship.

Quick Specs

  • Innovative Turbo Flange Design (Patent Pending) - 1/2" thick while retaining all OEM brackets
  • One-Piece Tube - Ensures exact fitment, robust construction and ease of installation
  • Smooth 3.5" to 3" Transition - Matches turbine outlet size and then reduces quickly to maintain exhaust velocity
  • 100% Made in the USA - Manufactured right here in Minnesota
  • Optimized Tube Routing - Maximize ground clearance and minimize flow restriction without modifying suspension hardware, etc
  • Custom Stainless Turbo Studs - Replace the terrible OEM studs and nuts with these, machined specifically for use with 2015 WRX turbine outlet and our 1/2" flanges
  • Standard 3rd O2 Bung - Allows the future use of aftermarket sensors
  • Grounding Strap Mount - Retains all factory functionality
  • 300 Cell Metallic Substrate Catalytic Convertor (Catted Models Only) - Excellent balance of the reduced restriction of a 'race cat' without the stink of a 200 cell unit

Includes everything

  • 1x Welded J-Pipe Assembly
  • 1x GrimmSpeed Stainless MLS Turbo to J-Pipe Gasket
  • 1x GrimmSpeed Stainless MLS J-Pipe to Catback Gasket

    J-Pipe

    This is the single best purchase I have ever made for the car. I have a Shinji e tune and it really brought the car to life. It feels great and has a nice rumble to it. Overall an amazing j pipe with solid construction.

    Quality Fitment

    Sounds amazing paired with the Invidia r400 CBE. Stock one is a pain to get out. Be patient, make sure you have the right tools and you’ll get it done. Out of all my mods this one I felt the biggest power increase. Buy it now!

    Easy install

    Super easy install (once you get the old one off) and it sounds amazing! The gains after my tune are definitely something else. It feels like a whole new car!

    Final Review

    First off, import had the best shipping, extremely fast. unfortunately, fedex being terrible like it is, gave me a really hard time getting this package, taking over a week past the original delivery date. And then to top it off, a week for the installation. If you have close to 90k miles and live in a rainy state, your going to have a ton of fun with the studs. Mine literally eroded off, and so we had to take a dremel and cut them off. After that, installation was super easy, and MAKE SURE you check if you need the adapter. got everything installed and realized i needed it. sad day. But overall, it makes the car sound way better and pop way more. I dont have my custom tune yet, but i will be running a AMBOTT stage 2 burble. Anyways. great product and would 10000000000% reccomend, worth every penny, coming from a 16 year old getting $8 an hour
