2022+ Subaru WRX Catless J-Pipe
2022–2025 Subaru WRX VB J-Pipe — Catless / Catted (GESI Catalytic Converter)
Function Fab Performance J-Pipe for the 2022+ Subaru WRX
Designed specifically for the VB-chassis 2022+ Subaru WRX, the Function Fab J-Pipe is engineered to improve exhaust flow while maintaining proper fitment and clearance with the factory turbocharger and surrounding components.
Each J-Pipe is designed, fabricated, TIG welded, and inspected in-house by Function Fab using 304 stainless-steel components and a laser cut turbo flange.
Choose between our Catless and GESI-catted configurations depending on your application and intended use.
Why Function Fab?
This isn’t a mass-produced universal exhaust component adapted to fit the VB WRX.
The Function Fab J-Pipe was designed specifically around the 2022+ Subaru WRX VB chassis with attention to:
* Turbocharger flange fitment
* Exhaust routing and clearance
* Factory mounting locations
* Downstream exhaust compatibility
* O2 sensor placement
* Proper tube transitions
* Serviceability and installation
The result is a J-Pipe designed to fit the car properly while giving you the quality and attention to detail you’d expect from a fabricated performance component.
