Do I need gaskets or hardware to install this?

You'll need exhaust manifold gaskets and stud bolts to complete installation. These are not included with the assembly — grab them separately to ensure proper sealing at the cylinder head.

Can I reuse my stock exhaust piping downstream?

Your existing exhaust piping should connect directly to the outlet on this assembly. Before installation, compare the outlet diameter and flange style to confirm fit — mismatches require an adapter or custom piping.

Should I wire-brush or clean the mounting surface before install?

Yes — remove carbon buildup and old gasket material from the cylinder head mounting surface with a wire brush or scraper. A clean surface ensures the new gasket seals properly and prevents exhaust leaks.
