Grimmspeed J-Pipe 2015-2021 Subaru WRX 6MT

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.

Quick Specs

• 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
