Frequently Asked Questions
Do I need new gaskets when installing this header?
Yes. Factory gaskets are single-use and won't seal properly on a second installation. Grab a fresh header gasket kit before you bolt this up.
Will this bolt directly to my stock exhaust piping?
The header uses factory mounting points, but you'll need to confirm your downstream exhaust piping aligns with the outlet diameter. Test-fit before finalizing connections.
Does this need any prep work before installation?
Clean the mounting surface on the cylinder head to remove old gasket material and dirt. No painting or coating work is needed — the stainless steel is ready to install as-is.
