Can you replace an exhaust manifold with a catalytic converter?

Can you replace an exhaust manifold with a catalytic converter?

If you’re looking for a replacement exhaust manifold, you may notice that the choices available for your specific vehicle are only available with an “integrated” catalytic converter. In the same way, a search for a replacement catalytic converter may only turn up “combination” converter/manifold products.

How are catalytic converters secured to the pipes?

As catalytic converters are usually sealed metal units by design, once they have failed they must be replaced. Typically, catalytic converters are secured in two ways: either bolted up at the flanges or welded directly into the pipes of the exhaust system.

What kind of exhaust manifold does Dec use?

The DEC Exhaust Manifold with Integrated Catalytic Converter. Integrated exhaust manifolds we sell (shown, the Walker Exhaust Manifold with Integrated Catalytic Converter) are designed to match OEM equipment.

When did they start putting catalytic converters in cars?

Catalytic converters have been installed in cars and light trucks since the mid-1970s. The catalytic converter cleans the vehicle’s exhaust gases before they are expelled from the exhaust pipe.

Can a straight pipe be used to replace a catalytic converter?

Before replacing your expensive catalytic converter, make sure it is the culprit by replacing it temporarily with a straight pipe, sometimes called a test pipe. If your car runs properly with the test pipe in place, your catalytic converter will need to be replaced soon. Park the vehicle on a level surface and raise it with a hydraulic jack.

Where is the exhaust manifold on a car?

The exhaust manifold refers to the manifold of tubes that connect from each piston, and bring the exhaust together to the main exhaust pipe. The catalytic converter is mounted on the main exhaust pipe further down.

Do I need to change the exhaust manifold when changing th?

But the quote includes the exhaust manifold which is 500 bucks. I wanted to know if it is absolutely necessary to change this as well. I just want to pass the emissions test. For a 2003 car, it’s too much an investment. My car has 232481 miles. My car has an automatic transmission.

Why do I need a CARB compliant exhaust manifold?

If you live in a CARB-following state, or if your vehicle was originally built to CARB emission standards, you’ll need to select exhaust components that are “CARB compliant”. This is particularly important when shopping for catalytic converters (or any exhaust sections containing them) which chemically change harmful gases into inert ones.

Why do you need a catalytic converter near the engine?

In case you’re wondering, in recent years many cars have the catalytic converter near the engine so they heat up faster. Catalytic converters are more effective after they heat up. That’s why car manufacturers integrate them into the exhaust manifolds. You probably need to replace it as a combination single unit. TN on November 02, 2019:
