Will these headers fit my stock exhaust manifold flanges?

Yes — these bolt to the factory cylinder head ports. No port matching or manifold modification needed. Swap your stock manifold for the header and gasket, then bolt it down.

Do I need to wrap or heat-shield these headers?

Not required, but it's common practice. Stainless resists oxidation without coating, so bare stainless is fine under the hood. Wrapping reduces underhood temps and protects adjacent components — your call based on engine bay layout.

What about passenger-side headers — are they sold separately?

This is a driver-side unit. Confirm whether your build calls for a full pair or single-side swap before ordering. Contact support if you need fitment guidance for your specific application.
