Do these headers require any exhaust modifications downstream?

Check your current exhaust piping diameter and collector outlet size before ordering. You may need to adapt or replace existing mid-pipe and cat-back components to match the header outlet.

Will I need new gaskets or seals?

Yes. Plan on replacing the header gaskets where it connects to the cylinder heads. Factory gaskets typically cannot be reused during installation.

What about heat shielding or insulation?

This header assembly does not include heat shields. Depending on engine bay layout, you may want to add aftermarket ceramic coating or header wrap to protect adjacent components from radiant heat.
