Second Hand Vauxhall Cavalier Exhaust Manifold

Yes, all Vauxhall Cavalier variants were fitted with an exhaust manifold — it is a standard component on every petrol and diesel engine the Cavalier was offered with, collecting exhaust gases from the cylinder head and routing them into the rest of the exhaust system. There is nothing unusual about the Cavalier's drivetrain layout that would mean any variant was built without one.

The Cavalier ran across two main UK generations — the Mk2 (1981–1988) and the Mk3 (1988–1995) — and the engine ranges changed significantly between them, so a manifold from the Mk2 era is very unlikely to cross over to a Mk3 without modification. Fitment of the exhaust manifold follows the engine code and the specific cylinder head it bolts to, both of which differed across these generations. Confirm the engine codes on both donor and recipient vehicles with the breaker before ordering across this boundary.

Trim level — whether GL, GLS, CDi, SRi, or GSi — does not affect exhaust manifold fitment on the Cavalier; what matters is the engine code and fuel type fitted to your specific vehicle. An SRi and a GL running the same engine will share the same manifold, though higher-performance variants like the GSi used different engines, so their manifolds will differ from a standard unit. Always match on engine code rather than trim badge.

No — the exhaust manifold is matched to the specific engine it was designed for, and the 2.0 and 1.8 petrol units used in the Mk3 Cavalier (1988–1995) have different cylinder heads and port configurations. Even where the engines share a family resemblance, the manifold gasket face, port spacing, and downpipe outlet may differ enough to prevent a straightforward swap. Always confirm the exact engine code with the breaker, not just the displacement.

No — petrol and diesel engines have entirely different cylinder head designs, combustion characteristics, and exhaust port layouts, so their manifolds are not interchangeable under any circumstances. Make sure you specify your fuel type clearly when requesting a quote from a breaker, as the donor vehicle must match on fuel as well as engine code.

Give the breaker your full registration number or VIN, your engine code (usually stamped on the block or visible on a sticker under the bonnet), and whether the car is petrol or diesel — these are the details that determine which manifold is correct. Trim level and colour are irrelevant to manifold fitment, so you do not need to mention those. A good breaker will cross-reference the donor vehicle's engine code against yours to confirm suitability before dispatch.
