GrimmSpeed 04-21 Subaru STI EJ25 2-Bolt Up-Pipe
$289.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2004-2021 Subaru STI (EJ25).
The GrimmSpeed 2-Bolt Up-Pipe is engineered to replace the restrictive factory unit, providing a more efficient path for exhaust gases to reach the turbocharger. By utilizing heavy-duty stainless steel and precision-machined flanges, this up-pipe eliminates common leak points and stands up to the extreme thermal cycling of the EJ25 engine. This upgrade is essential for improving turbo spool and ensuring long-term reliability on high-performance builds.
- Designed as a direct replacement for the factory 2-bolt up-pipe
- Heavy-duty stainless steel construction for superior heat and corrosion resistance
- Thick flanges prevent warping and ensure a flat, leak-free mating surface
- Optimized internal diameter improves exhaust gas velocity
- Manufacturer Part Number: GRM.1099.1.SS
