Do I need gaskets or fasteners to install this?

Hardware is not included with the assembly. You'll need exhaust gaskets for the manifold flange connection and bolts matching your vehicle's factory specs. Check your service manual or have a tech verify the exact bolt pattern before ordering fasteners.

Can I reuse my OEM exhaust piping after swapping this in?

Yes, the bolt-on design connects directly to your existing downpipe and exhaust system. Test-fit it before final tightening to make sure alignment is tight with your current setup.

What if this doesn't seal properly after installation?

A leaking exhaust manifold joint usually means the gasket is worn or the flange bolts weren't torqued evenly. Tighten in a crosshatch pattern and refer to your service manual for the correct torque spec. If leaks persist, the OEM gasket surface may need resurfacing.
