What It Helps Address

• Exhaust leaks at the front pipe flange

• Soot marks around the exhaust joint

Installation Notes

Verify the vehicle’s emissions configuration before ordering: 1986-1987 Nissan Sentra Federal Emissions Equipped and 1988 Nissan Sentra California Emissions Equipped Vehicles Registered Outside Of California. Confirm the front pipe inlet location and 3-bolt flange pattern before installation. Clean the mating surfaces thoroughly so the gasket can seat evenly and seal properly.
