Nissan 370Z Exhaust Manifold Replacement Parts

The 370Z does have exhaust manifolds — on this model they are tubular headers rather than a cast iron log-style manifold, but the part is still correctly called an exhaust manifold and is a standard fitment on the 3.7-litre VQ37VHR V6 petrol engine used across all UK 370Z variants. Because the VQ37VHR is the only engine offered in the UK 370Z, every car has them — one on each cylinder bank (near-side and off-side). There is no diesel or alternative engine variant to complicate things on this model.

The 370Z ran from 2009 through to around 2021 in the UK, with a facelift arriving for the 2013 model year, and the VQ37VHR engine carried through the entire production run without a fundamental change to the exhaust manifold design. In principle the manifolds are closely related across that boundary, but whether a specific used unit from a pre-facelift car will bolt directly onto a post-facelift car without modification is something you should confirm with the breaker against your exact registration, as minor packaging or sensor-port differences can exist. Never assume a used manifold will fit without that check.

Trim level does not determine which exhaust manifold you need on the 370Z — the GT, GT Edition, and Nismo all share the same VQ37VHR engine, and the exhaust manifolds follow the engine, not the trim. The Nismo version does have a distinct performance exhaust system, but what you may find cosmetically different (mid-pipes, rear silencers) sits further downstream; the manifolds themselves attach to the same cylinder head. Source a manifold matched to your engine code and model year, and trim is not a factor.

Because the VQ37VHR is a V6, it has two separate exhaust manifolds — one for the near-side (NS) bank and one for the off-side (OS) bank — and they are not interchangeable with each other. You can buy and replace just one side, which is the most common approach when only one manifold is cracked or damaged. Make sure you specify to the breaker whether you need the NS or OS manifold, and confirm it comes from a car of the same engine code and model year as yours.

On many 370Z setups the catalytic converters sit very close to, or are integrated with, the downpipe section just after the manifolds, so what a breaker lists as an 'exhaust manifold' may or may not include the cats depending on how the car was stripped. Whether a used unit includes functioning catalytic converters, and whether those cats will pass a UK MOT on your specific car, is strong confirm-with-breaker territory — ask the breaker explicitly what is included and verify it against your registration before purchasing.
