Grimmspeed 2-Bolt Up-Pipe | EJ25 (GRM.1099.1)

Description

2-Bolt Up-Pipe for EJ25 by Grimmspeed

Adding a properly designed, thoroughly tested up-pipe is one of the most effective early mods you can make to your Subaru. GrimmSpeed’s goal was to create a 2-bolt up-pipe that checks every box: precise fitment, long-term durability, strong performance gains all while meeting modern emissions standards. The result is a SEMA Certified component engineered to deliver on all fronts.

This up-pipe was developed entirely in-house using a FARO Arm and advanced SolidWorks CAD software, giving Grimmspeed complete control over every detail from material selection to final fitment. The result is an OEM-header-compatible up-pipe with dead-on accuracy, thanks to ” CNC-milled stainless-steel flanges and reverse-engineered tolerances based on real-world data.

Each unit is packaged with a set of proven GrimmSpeed Fire Ring multi-layer steel gaskets and corrosion-resistant zinc-coated hardware no extra parts or trips to the parts store required. Everything you need is in the box

Please Note: SEMA Certified SC-GRM01-0145 for listed fitments, currently in the process of obtaining a CARB EO #.
