Will this header work with my OEM cat-back exhaust?

The header bolts to your factory exhaust manifold location. Verify your downpipe connection matches standard D17A2 dimensions before ordering.

Do I need a gasket or sealant between the header and engine block?

Use a quality gasket kit designed for D17A2 headers. Do not rely on adhesive alone—proper gaskets prevent exhaust leaks and thermal cycling damage.

Can I install this myself with basic hand tools?

Header installation requires engine bay access, jack support, and wrench work to remove heat shields and disconnect the OEM manifold. Refer to your service manual for proper torque specs and removal sequence.
