02-06 Nissan Sentra 2.5L Header Stainless Steel

Do I need to use sealant or gasket material when installing this?

Use a quality exhaust gasket at the engine flange connection point. Do not rely on sealant alone — gaskets are the standard method for sealing header-to-engine joints and prevent exhaust leaks.

Will this bolt directly to my factory exhaust manifold mounting points?

This header is designed to replace the factory manifold and mount at the original engine port locations. You'll need to verify bolt hole alignment and any exhaust piping connections on your specific vehicle setup before finalizing installation.

Does this header require ceramic coating or can I leave it bare stainless?

Bare stainless steel will not discolor or rust — coating is optional. Many owners leave it uncoated for the raw finish look, while others apply high-temp ceramic coating for heat management and aesthetics. Either approach works with stainless construction.
