GReddy 80mm Oval Exhaust Gasket for 1989-2002 Nissan 240SX Silvia SR20DET Subaru Impreza WRX
The GReddy 80mm Oval Exhaust Gasket provides a multi-layer steel seal for high-performance exhaust manifolds and downpipes on Nissan SR20DET 240SX and Silvia models from 1989 to 2002, plus Subaru Impreza WRX 2002-2007. This gasket withstands extreme heat over 1600°F and high pressure from turbocharged engines to stop exhaust leaks and preserve boost levels. It serves as a direct replacement for worn stock gaskets in tuned exhaust setups.
Key Features
- Multi-Layer Steel Build: Stainless steel layers flex to seal uneven flanges and resist blowouts during high exhaust flow
- 80mm Oval Design: Matches port size on GReddy turbo manifolds for SR20DET and EJ20/EJ25 turbo applications
- High-Temperature Resistance: Handles over 1600°F for consistent performance in turbo systems
- 4-Bolt Pattern: 70mm x 52mm spacing fits JDM performance flanges directly
- Thin Profile: 1.6mm thickness reduces exhaust restriction with secure compression
Product Notes
- Inspect manifold and downpipe flanges for flatness before installation
- Torque bolts to 20-25 ft-lbs in cross pattern for even clamping pressure
- Store in dry area to prevent corrosion on steel layers
Installation Notes
- Professional installation recommended.
- Clean mating surfaces with wire brush and degreaser for optimal seal
- Compatible with OEM or GReddy hardware replace studs if stretched
