Used Nissan Skyline Exhaust System

The R32 Skyline ran from 1989 to 1993 and the R33 from 1993 to 1998, and while both generations share a broadly similar layout, the engine codes differ — the R32 used the RB20DE, RB20DET, and RB26DETT, while the R33 used the RB25DE, RB25DET, and RB26DETT — so exhaust sizing and manifold routing are not the same across those generations. A system from the wrong generation is unlikely to be a straight swap even if it looks similar. Always confirm with the breaker using both your registration and the specific engine code before purchasing.

The R34 ran from 1998 to 2002 and the R33 from 1993 to 1998, and although both generations used RB-series engines including shared codes like the RB25DET and RB26DETT, the chassis dimensions and exhaust routing differ between generations. Sharing an engine code does not guarantee the system will mount correctly on a different generation body. Confirm fitment against your specific registration and engine code with the breaker before buying.

Trim level alone does not determine exhaust fitment — what matters is the engine code and the generation of the car, not the badge on the boot. That said, the GT-R (RB26DETT twin-turbo) and the GTS-T (RB25DET) use entirely different engines, so their exhaust systems are genuinely different — but that difference is driven by the engine, not the trim name itself. When sourcing from a breaker, always quote your engine code rather than just the trim level to make sure you get the right system.

The vast majority of Skylines in the UK are Japanese domestic market (JDM) imports, and the exhaust system is determined by the engine code and generation rather than the destination market, so fitment rules remain the same. However, UK emissions regulations and MOT requirements still apply, and a system that does not retain the correct catalytic converter for your car's era may cause an MOT failure. Confirm with the breaker that any used system includes the appropriate emissions components for your specific engine and registration year.

The R33 Skyline received a facelift in 1995, but changes were largely cosmetic and the engine codes remained consistent across the pre- and post-facelift cars, so in many cases the exhaust system is the same throughout the 1993 to 1998 production run. That said, confirming whether a specific system crosses the facelift boundary correctly is best left to the breaker, who can check your registration against the part they have. Never assume a visual match means a correct fit without verification.

For a used exhaust system to pass a UK MOT it must be in sound condition and, critically, must retain the correct catalytic converter for the car — an MOT tester will check emissions output, and a missing or wrong-era catalyst can cause an immediate failure. Whether a specific used system carries the right catalyst for your engine and registration year is something you must confirm directly with the breaker, as interchange specifics vary. Do not assume a system from the same generation automatically meets your car's emissions requirements without checking.
