Will this bolt directly to my stock manifold location?

Yes. This header uses factory mounting points — no drilling or chassis work. You'll use existing studs and bolt holes.

Do I need a new downpipe or O2 sensor bung?

Confirm your current downpipe flange and O2 sensor location before ordering. Headers can sometimes require downpipe adapter fitment depending on your setup.

Should I ceramic coat or paint this before installation?

Not required. Bare stainless will oxidize to a dark gray patina over time but won't rust. If you prefer a finished look, ceramic coating is optional and should be applied before install.
