Right Axle-Back Exhaust/Muffler Assembly - 1990 300ZX Z32

The right axle-back muffler assembly for the 1990-1996 Nissan 300ZX Twin Turbo (Z32) terminates the VG30DETT's distinct twin exhaust layout. OEM reference 20100-40P05 covers 1990-1996 production for the passenger-side axle-back section, distinct from the left-hand unit (20100-30P05). Junkyard hunters should target 1990-1996 Z32 chassis with the VG30DETT engine; naturally aspirated models utilize a completely different single-exit configuration unsuitable for turbo applications. Inspection requires checking the three-bolt spring flange connection at the Y-pipe junction for seizure and galvanic corrosion, as these hardware assemblies often require torch cutting for removal. Examine the muffler canister for seawater corrosion perforations common in coastal regions and verify the four rubber hanger isolators aren't torn or sagging. Installation necessitates new composite gaskets and copper antisieze compound on all hardware to prevent future seizure. Note that 1994-1996 OBD-II models may feature additional oxygen sensor bungs, potentially requiring verification before interchange with pre-1994 examples.
