Do I need new gaskets and fasteners to install this?

Yes. You'll need a fresh header gasket set and matching studs or bolts. The factory hardware may not seal properly a second time, so plan to replace those pieces as part of the install.

Does this header need to be painted or ceramic coated before installation?

Stainless steel doesn't require coating to prevent rust, but some builders ceramic coat for heat management and aesthetics. Paint or coating is optional — this header ships bare stainless and ready to bolt on as-is.

What about the oxygen sensor bung — does it match my OEM location?

Confirm O2 sensor placement against your current exhaust manifold before ordering. Header design may vary, and sensor location matters for CEL codes and tuning compatibility.
