Exhaust Pipe Flange Gasket for OE-Style Repairs

Walker 31386 is an exhaust pipe flange gasket built for sealing converter-to-Y-pipe and related exhaust joints on a wide range of Nissan, INFINITI, and select other applications. It uses a fiber construction with a steel core and metal fire ring to help maintain a tight seal at the flange connection.

With a 2-bolt design, slotted bolt holes, and a 0.125-inch thickness, this gasket is sized for common exhaust flange service where alignment and sealing are critical. It is a practical choice for repairs on vehicles such as the Nissan 370Z, INFINITI G37, and INFINITI Q50, and it is engineered to work with OE exhaust components and Walker aftermarket replacement parts.

Detailed Description

Walker 31386 is designed for exhaust repair jobs that require a reliable seal at the flange connection. The fiber body, steel core, and metal fire ring help support the joint under exhaust heat and vibration, while the slotted bolt holes make positioning easier during service. This part number is commonly used in converter-to-Y-pipe applications across many Nissan and INFINITI platforms, including the 2009-2017 Nissan 370Z, 2009-2013 INFINITI G37, and 2014-2015 INFINITI Q50. Walker 31386 is also listed for additional applications such as the INFINITI Q70, Q70L, QX70, M35, M37, FX35, G35, and select Nissan 350Z and Pathfinder exhaust connections.

This part cross-references BRExhaust 256-390 for the same application.

Common Repair Uses

  • Exhaust leak at a converter-to-Y-pipe flange
  • Noise from a damaged or flattened exhaust gasket
  • Loss of seal after exhaust service or component replacement
  • Fitment issues caused by worn flange sealing surfaces
  • Replacement for a deteriorated 2-bolt exhaust pipe flange gasket

Installation Notes and Tips

  • Confirm flange style, port size, and bolt spacing before installation.
  • Clean both mating surfaces to remove carbon, rust, and old gasket material.
  • Align the slotted bolt holes carefully before tightening the flange.
  • Use the listed vehicle position for the exact exhaust location, such as right converter to Y-pipe or left converter to Y-pipe.
  • Verify application details for vehicles with notes such as without California Emission System or without Traction Control.
