Header Gasket.
Category: Extractors and headers


The Redback DSF057 is a header gasket listed to fit the Toyota 21R-C engine as used in the Bundera, Celica, HiAce and Hilux. It is the seal between the cylinder head and the header or exhaust manifold flange, not an exhaust component in its own right.
A header gasket is the flat seal clamped between the engine’s exhaust port face and the header (extractor) or manifold flange. Its job is to contain hot exhaust gas at that joint so the system stays sealed and leak-free. Because it is keyed to the engine’s port pattern rather than the body, one gasket can suit several models that share a motor — here the Toyota 21R-C. It is a wear item, renewed whenever the flanges are unbolted.
It is listed to fit the Toyota 21R-C engine across the Bundera, Celica, HiAce and Hilux. The common thread is the engine, so the right gasket depends on confirming your motor is the 21R-C and that your flange pattern matches. Confirm the exact build with the workshop before ordering.
A header gasket seals a joint and is not an emissions or compliance component, so it does not alter a vehicle’s road status on its own. The legality of the exhaust comes down to the headers or manifold and the rest of the system it seals against, not the gasket itself.
Oak Flats Muffler Men fits and seals header joints in-house across the Illawarra. We confirm the gasket matches your 21R-C port face, check the flange is flat, and torque the joint evenly so it seals cleanly. At an RRP of $10.59 it is an inexpensive part well worth renewing when the headers come off. Tell us which 21R-C Toyota you’re running and we’ll confirm fitment.
