Grimmspeed Up Pipe – 2-Bolt | Black Ceramic Coating | Subaru EJ Turbo | 2004+ STI / 2002+ WRX / 2005+ Legacy GT / 2009+ Forester XT

Eliminate the factory up pipe restriction on your EJ-powered Subaru with the Grimmspeed Up Pipe — 2-Bolt configuration with a durable black ceramic coating for superior heat management and long-term corrosion resistance. The factory up pipe is a well-known exhaust flow bottleneck on the EJ platform, with a restrictive catalytic converter and suboptimal geometry that limits exhaust flow and turbo spool. Grimmspeed's up pipe replaces the factory unit with a free-flowing design, and the black ceramic coating adds a layer of thermal protection that reduces underhood heat soak and protects the pipe from corrosion and oxidation for long-term durability.

Key Features

• Black Ceramic Coating: Durable black ceramic coating provides superior heat retention within the exhaust stream, reduces underhood radiant heat, and protects the pipe from corrosion and oxidation for long-term durability and a clean appearance
• 2-Bolt Flange: 2-bolt flange configuration for a secure, leak-free connection — verify flange compatibility with your specific downpipe before ordering
• Eliminates Factory Up Pipe Restriction: Replaces the restrictive factory up pipe and its integrated catalytic converter — a well-known exhaust flow bottleneck on the EJ platform — with a free-flowing alternative
• Improved Turbo Spool: Reduced exhaust backpressure improves turbo spool response for faster boost build and improved power delivery across the RPM range
• Broad EJ Platform Coverage: Fits the EJ-powered Subaru WRX (2002+), WRX STI (2004+), Legacy GT (2005+), and Forester XT (2009+)
• Grimmspeed Quality: Manufactured by Grimmspeed — a trusted name in Subaru performance parts with a proven track record on the WRX and STI platforms
