Sold as a pair covering both the left-hand and right-hand manifold-to-crosspipe (uppipe) junctions. Seals the interface where each cylinder bank’s exhaust manifold connects to the crosspipe\/uppipe that collects both exhaust streams en route to the turbo. 0.18 lbs.

There are two of these joints — one per cylinder bank — which is why this gasket is sold as a pair. The crosspipe then routes the combined exhaust stream up to the turbo’s turbine housing inlet, where a separate gasket (the uppipe-to-turbo gasket, GrimmSpeed 024001) seals that final junction. The GrimmSpeed 025001 covers the manifold-to-crosspipe end; the 024001 covers the crosspipe-to-turbo end. For a complete crosspipe\/uppipe service, both gasket sets are typically required.\u003c\/p\u003e\n\n\u003ch3\u003ePair — Both Banks Covered\u003c\/h3\u003e\n\u003cp\u003eThe EJ boxer engine has two cylinder banks and two exhaust manifolds, each connecting to the crosspipe at its own flanged joint. The 025001 is sold as a pair to cover both LH and RH manifold-to-crosspipe junctions in a single purchase. Do not assume a single gasket is sufficient for a full crosspipe replacement or manifold removal — both joints must be sealed.\u003c\/p\u003e\n\n\u003ch3\u003eCommon Replacement Scenarios\u003c\/h3\u003e\n\u003cp\u003eReplace these gaskets during: crosspipe\/uppipe replacement (aftermarket uppipe installation is one of the most common EJ modifications — the OEM uppipe’s catalytic converter is a flow restriction and boost leak point), exhaust manifold removal, exhaust leak diagnosis at the manifold-to-crosspipe junction, and engine rebuild. Best practice: always install new gaskets when any manifold or crosspipe flange is separated.\u003c\/p\u003e\n\n\u003ch3\u003eEJ Platform Fitment\u003c\/h3\u003e\n\u003cp\u003eFits Subaru EJ-platform turbocharged engines: WRX (EJ205 \/ EJ255, 2002–2014), WRX STI (EJ257, 2004–2021), and Legacy GT (EJ255, 2005–2009).
