This Exhaust Systems Australia steel header gasket is listed to fit the Toyota 1Y, 2Y and 3Y petrol engines. The MPN is TOYOTA-1Y-2Y-3Y-PETROL-STEEL-HEADER-GASKET. It's the flange seal, not a header.
What is a steel header gasket?
A header gasket seals the joint between the cylinder head exhaust ports and the header or extractor flange, so the exhaust leaves through the pipe rather than weeping out at the flange. A steel gasket suits the heat cycling that joint sees on the Y-series petrol fours. It's a consumable — replaced when the headers come off rather than reused.
Will it suit my Toyota Y-series engine?
It's listed to fit the Toyota 1Y, 2Y and 3Y petrol engines. Because the gasket has to match the head's port pattern, send the workshop your engine code and we'll confirm it's the right gasket before you order. Treat it as listed to fit rather than guaranteed, since feed data can be imperfect.
When do I replace it?
Any time the extractors or headers are unbolted from a Y-series head, fit a new gasket. A reused steel gasket that's already been crushed tends to leak at the flange and tick under load. On a job that's already apart, a fresh gasket is cheap insurance against a comeback.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits Toyota exhaust hardware across the Illawarra, checking the flange faces are clean so the new gasket seals. At $10.30 AUD RRP it's a small consumable worth ordering alongside any header work; listed to fit the 1Y, 2Y and 3Y petrol engines, confirm your engine with us.

Common questions
Which engines does it suit?
The Toyota 1Y, 2Y and 3Y petrol engines. Confirm your engine code with the workshop.
Is this a header or just the gasket?
Just the gasket — the steel flange seal between the head and the headers.
Do I need a new one when fitting extractors?
Yes. Once the headers are off, the gasket should be replaced so the flange seals cleanly.
