Seal a leak-prone Subaru exhaust connection
GrimmSpeed GRM026001 replaces the gasket between the exhaust manifold and up-pipe on Subaru EJ turbo applications. Its seven-layer stainless construction is designed to maintain a reliable seal where thin or mixed-material gaskets can deteriorate and leak.
Key Features
- Seven-layer multi-layer steel construction
- 304 stainless steel fire ring
- Approximately 22 percent thicker than the OEM gasket
- OEM-style shape for the manifold-to-up-pipe connection
- Designed for Subaru EJ turbo applications
- Sold individually
Fitment
| Application | Compatibility requirements |
|---|---|
| Subaru EJ turbo exhaust systems | GrimmSpeed lists this gasket for all EJ Subaru turbo applications at the exhaust manifold-to-up-pipe joint. Confirm the engine uses the matching two-bolt manifold and up-pipe flange. This is not the thicker twelve-layer version, an up-pipe-to-turbo gasket, or a universal exhaust gasket. |

FAQ
What is the GRM026001?It is GrimmSpeed's seven-layer gasket for the Subaru EJ turbo exhaust manifold-to-up-pipe connection.
Is this the twelve-layer extra-thick gasket?No. That is a different GrimmSpeed part. This listing is for the seven-layer version that is approximately 22 percent thicker than OEM.
What is the fire ring made from?GrimmSpeed specifies a 304 stainless steel fire ring.
How many gaskets are included?One gasket is included.
Does it fit every Subaru engine?No. The manufacturer specifies EJ Subaru turbo applications with the matching manifold-to-up-pipe flange.
Can it replace an up-pipe-to-turbo gasket?No. The two exhaust joints use different gaskets and must be matched separately.
Should the mating flanges be inspected?Yes. Both flanges should be clean, flat, and free of damage that could prevent sealing.
Are replacement fasteners included?No. Inspect the existing hardware and obtain application-correct replacements when required.
Installation Instructions
- Allow the exhaust system to cool completely and support the vehicle using approved procedures.
- Confirm the engine and flange pattern match the manufacturer's EJ turbo application before disassembly.
- Remove the old gasket and clean both mating flanges without gouging their sealing surfaces.
- Inspect the flanges and hardware, position the new gasket correctly, and assemble the joint without sealant unless the current manufacturer procedure requires it.
- Tighten fasteners in an even sequence to the applicable service specification, then check for leaks after the first heat cycle.
