Frequently Asked Questions
Do I need to replace my exhaust manifold gasket when installing this?
Yes. The factory gasket compresses during removal and won't seal properly on reinstall. Pick up a new one before you start — you'll need it to prevent exhaust leaks at the head.
Does this header come with a heat shield?
Header assembly only. Heat shielding is sold separately and depends on your engine bay layout and what components are nearby — measure your clearances before ordering.
Will I need a custom exhaust tune after installing this?
This header flows better than stock, which can affect your air-fuel ratio. If you're running a tune already, verify compatibility with your tuner. If you're staying completely stock otherwise, most drivers report no issues, but monitor your fuel trim if you have a scan tool.
