What it does
The exhaust manifold or header collects exhaust from each cylinder and sends it into the exhaust system. Exhaust parts carry gases away from the engine; replacing rusted or restrictive parts fixes leaks and noise, and performance designs can add flow and sound.
Installation & tips
- Use new gaskets and studs, and check emissions rules where you live before changing headers.
- Exhaust manifold gaskets: Always new.
- Studs and nuts: Old studs often break on removal.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
