Many people want to try to remove catalytic converter from their vehicle. They think that this is a good idea so that they can get better gas mileage as well as improve the vehicle’s horse power. Each vehicle varies greatly, but you can remove catalytic converter from any car. It is pretty easy process to take it off the vehicle. Here are the steps you will need to take to get it off your vehicle.
More exhaust backpressure generally means less horsepower, and a stock catalytic converter is often the greatest source of backpressure in an exhaust system. So it’s no wonder the catalytic is often tossed in favor of an eBay “test pipe” when a performance-minded owner starts itching for a little more power. But there are a few downsides to de-catting a car – the big one being that it’s illegal.
Just to be safe, make sure the vehicle is parked on a solid piece of ground where it can be jacked up safely. Then use the proper jacks for your vehicle and raise the vehicle off the ground. You will need to get under the car to remove your catalytic converter. From underneath the vehicle you should be able to see the exhaust pipe running along the middle of the undercarriage. About the middle of the way back you should be able to see the cat. It looks like a wide area and is probably a rectangular shape. It should be located just in front of the muffler.
My friend swears that if you remove or hollow out your catalytic converter, your car will get a major boost in power, especially if its a 4 cylinder engine. Is this true or an urban legend?Answer:It is true, but also illegal for street operated vehicles.
Stay legal and replace it with a high flow catalytic. Which most shops will and can install for you.
Carefully assess how the cat is attached to the muffler and the manifold. Most of the time it will be attached using four bolts. Two are located toward the front and two toward the back; all of which need to be removed. You will need the right size of socket to take them out easily. Using a socket (or a wrench) and a ratchet you can remove all four of the bolts from around the unit. Be careful to not strip out the bolts. You may need to use a lubricant on some models to remove the bolts easier. If the bolts are too corroded, you will need to cut the bolt heads off to remove the unit. After the bolts have been removed you should be able to remove bad catalytic converter from the undercarriage of the car.
- Park your vehicle on flat, solid ground for safety purposes. Jack the vehicle up and place it on jack stands.
- Get under the vehicle in the middle area and look along the exhaust pipe until you spot the catalytic converter. It will look like a wide area of the exhaust pipe, sometimes square or rectangle shaped (not the muffler towards the rear of the vehicle).
- Look to see how the catalytic converter is attached. There are probably four bolts, two in front and two in the rear, that can be removed. Check the size of the bolts and make sure you have a socket to fit them.
- Use a ratchet and socket or wrench to remove the four bolts from around the catalytic converter. In some cases, the bolts are corroded and must be cut off with a saw and drilled out. If this occurs, be careful to only cut the bolt heads.
- Pull the catalytic converter from the exhaust and it should be out completely.
There are times when it is better to call a mechanic. If for some reason the bolts will not come out or you have any difficulty, it is better to have a qualified and experienced mechanic take it off for you. This will ensure that there is no damage to any other parts of the vehicle. It is also advisable to check with the laws in the state in which you live. Some states, such as California, have legislation that forbids an owner from trying to remove catalytic converter from their vehicle.
