2022 Subaru XV exhaust gasket — purpose, replacement and maintenance

Based on Subaru’s own technical documentation, exhaust gaskets are absolutely used on the 2022 Subaru XV. The Subaru Service Manual for the XV/Crosstrek (GT platform, MY2022) in the Exhaust System section illustrates gaskets at the cylinder head–exhaust manifold joint and at the manifold–front pipe joint. The Subaru FAST electronic parts catalogue for the GT-series XV likewise lists “gasket—exhaust manifold” and “gasket—exhaust pipe (front, donut type)” for the FB20 and FB20 e‑BOXER engines. With those factory sources, an exhaust gasket is relevant, fitted, and serviceable on the 2022 Subaru XV.

On this model, the exhaust gasket’s job is to seal hot gases as they leave the boxer engine and pass through the manifold, front pipe and catalytic converter. A tight seal keeps the emissions system working as intended, avoids that tell-tale ticking or hissing on cold start, and prevents fumes making their way under the cabin. It also protects oxygen sensor readings so the engine management can keep fuel economy and drivability on point.

Exhaust gaskets on a 2022 XV are generally long-lived. They’re best treated as single‑use whenever a joint is split during other work (for example, clutch, transmission or catalyst replacement). The manifold-to-head gasket is a multi‑layer steel type designed to handle heat cycles, the front pipe typically uses a crushable or graphite “donut” gasket with spring‑loaded bolts to maintain clamp load as things expand and contract.

• When to replace: whenever a joint is disturbed, if there’s audible leak, visible soot at a flange, or exhaust odour around the front of the car.
• Good practice: use OEM‑quality gaskets, renew spring bolts at the front pipe if corrosion is present, and clean mating faces so the new gasket beds properly.
• Torque and fitment: follow the service manual torque and sequence for the manifold fasteners, align the system on its hangers before final tightening, and avoid over‑torquing which can warp flanges.

For Australian and New Zealand conditions—coastal air, corrugations, and big kilometre road trips—regular inspections pay off. A quick check at service time for soot trails, loose heat shields and perished hangers helps the gaskets live longer. If a light tick is heard on cold start that quietens when warm, or if fuel economy dips with no obvious cause, an exhaust leak check around the manifold and front pipe is a smart next step.

Done right, replacing the 2022 Subaru XV exhaust gasket restores a quiet note, keeps emissions in check, and saves future headaches with sensors and fuel trim.

Popular questions

Does the 2022 Subaru XV have exhaust gaskets from factory?
Yes. Factory literature for the GT‑series XV shows gaskets at the manifold-to-head and manifold-to-front pipe joints. These seals are integral to exhaust sealing and emissions performance on both the standard FB20 and the e‑BOXER hybrid variants.

How often should exhaust gaskets be replaced on a 2022 XV?
There isn’t a time or kilometre interval. They’re replaced if a joint is separated during other work, or if symptoms of a leak appear. In normal service they can last many years, but any audible leak, soot at a flange, or exhaust odour warrants inspection and likely renewal.

What are the signs of a blown exhaust gasket on a 2022 Subaru XV?
Common signs include a ticking or hissing noise on cold start, black soot around a flange, a sharper or raspy exhaust note, exhaust smell near the engine bay, and sometimes fuel trim or O2 sensor faults. Left unattended, leaks can affect fuel economy and make the car less pleasant to drive.
