Do these require new exhaust clamps or gaskets?

You'll need to source new gaskets for the header-to-manifold flange connection — don't reuse the old ones. Clamp hardware is not confirmed as included, so grab quality stainless clamps before install day.

Will these fit my existing exhaust system?

Header outlet diameter is not specified, so confirm the outlet size matches your downstream exhaust pipe before ordering. A quick measurement at a muffler shop prevents costly fitment surprises.

Should I paint these before installation?

Stainless headers can stay bare — they won't rust — but many owners coat them with high-temp paint for appearance. If you paint, do it before bolting on to avoid overspray inside the engine bay.
