With the 2015+ WRX J-pipe, the devil is truly in the details and the product development team 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.
- Innovative Turbo Flange Design - 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 Converter - Excellent balance of the reduced restriction of a 'race cat' without the stink of a 200 cell unit. Note this this is NOT a GESI cat; this is the Version 1 (V1) of this J-pipe.
Fits 2015-2021 Subaru WRX with 6-speed manual transmission only. Does NOT fit CVT models.
