GrimmSpeed J-Pipe 3in Catted-(Subaru WRX 2015+)

Good Vibes Performance is proud to offer you the best upgrades brought to you by GrimmSpeed. Whether it's a boost controller, replacing gaskets or you're upgrading your up-pipes/down-pipes, we have it here. Get those numbers up and share the Good Vibes.

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. 




  • 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
