Will this header fit my stock exhaust system?

The header connects to your existing exhaust manifold outlet. Test your downpipe fitment before final installation — aftermarket piping may require adapter work depending on your setup.

Do I need to remove anything else to install this?

You'll need to remove your factory manifold and any heat shielding in the way. Have jack stands, basic wrenches, and a jack ready. Expect 1-2 hours for most DIYers.

Does this come with gaskets or fasteners?

Header assembly ships as pictured. You'll want new exhaust gaskets (flanged style) and stainless bolts for the flange connection — those are not included.
