Frequently Asked Questions
Do I need gaskets or new fasteners to install this?
You'll want a new manifold gasket between the cylinder head and this assembly—reusing the old one risks exhaust leaks. Fasteners aren't included, but the bolt pattern is OEM-spec, so standard hardware from any auto parts store works.
Will this pass emissions?
Yes. The integrated catalytic converter meets emissions standards for these model years. Once installed, your vehicle is equipped with a functioning converter.
Can I install this myself, or do I need a shop?
If you're comfortable unbolting and rebolting a manifold, you can handle this. Main work is draining coolant (if your layout requires it), removing the old manifold, and bolting the new one in place. A jack, basic wrenches, and a gasket scraper are all you need. No special tools required.
