SKU: 11000305

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
