Will I need new gaskets or fasteners to install this?

The header assembly ships without gaskets or mounting hardware. You'll need exhaust gaskets and stainless steel bolts to complete the install — these are wear items and should be replaced regardless of whether you're keeping factory headers or swapping to new ones.

Can I run this header straight into my stock exhaust system?

Header outlet diameter and stock exhaust flange compatibility depend on your specific truck configuration. Test-fit before committing — you may need a transition pipe or mild exhaust work downstream to avoid leaks or fitment issues.

Does this header need to be painted or coated?

Stainless steel won't rust bare, but the exterior surface can discolor from heat cycling. Many builders coat headers with high-temp paint or ceramic for appearance — optional, not required for durability.
