Frequently Asked Questions
Do I need new gaskets and bolts when installing this header?
Yesβyou'll want fresh header gaskets to seal properly at the head. Reusing old gaskets risks exhaust leaks. Mounting bolt spec depends on your engine's service manual; have those on hand before you start.
Can I bolt this directly to stock exhaust, or do I need new piping?
The collector outlet diameter determines what fits downstream. Test-fit the header to your existing exhaust before final installβyou may need an adapter or custom section to avoid gaps or interference.
Does this header need ceramic coating or heat wrap?
Stainless resists corrosion on its own, but heat management is up to you. Many builders wrap headers for underhood temperature control and sound isolationβneither is required, but both improve longevity and comfort.
