Article: From the start, you need a strong argument for ending the relationship, so you can make sure you follow through. Get real with yourself and take some time to write out all the reasons this relationship is toxic and needs to end. One of the most important reasons to leave a toxic relationship is because you deserve better. In addition, the relationship may be preventing you from growing, isolating you from others, or becoming borderline or full-on abusive. Go over what you want to say to the person beforehand. This will help you to appear more confident when you have the talk.  You can rehearse in front of a mirror or with a friend. Rehearsing can help you feel more confident when you speak, but keep in mind the conversation may go differently than you rehearsed. Give the person advance notice that you want to have a conversation and ask them when they are available to talk. Depending on how safe you feel, consider reaching out in person, over the phone, or via text. You might say, "Hey, I need to talk to you about something important. Do you have time to get together?" Have a face-to-face discussion with the person, if possible. Set the location based on how you expect the conversation to go. For example, if the person is likely to become angry, have the conversation in a public place. If this is an abusive relationship, have the talk by phone or through video call for your safety. Be direct about what's not working in the relationship and your decision to end it.  You might say something like, “I don't think we're good together. We breakup and makeup all the time and I have started to alienate other people who are close to me. I want to end it.” Another option is to say something like, "Our relationship is not working for me. I've thought it through, and I want to end it." There's a good chance the other person will have quite a mouthful to say. Listen to what they have to say as long as their response is free of insults or threats.  If they try to convince you not to end it or some other tactic, simply restate your decision. Be as clear and concise as possible. If they become angry or argumentative, say “I didn't come here to argue. I'm leaving. Please don't follow me.”

The oxygen sensors are small metal pieces attached to wires that connect into the sides of the exhaust pipe. Place a wrench around the bolt connecting the sensor to the pipe and rotate it counterclockwise until it’s loose. Pull the oxygen sensor straight out from the pipe before unplugging it from the wires connecting to your vehicle.  Your vehicle will usually have 1–2 oxygen sensors connected to the exhaust, but it may vary between make and model. Vehicles only have oxygen sensors if they have a catalytic converter. If your vehicle is from 1974 or prior, then the exhaust may not have oxygen sensors. Lie on a rolling creeper trolley to move around under your vehicle more easily. You can buy a creeper trolley from an automotive supply store. Wear clothes that you don’t mind getting dirty as well as disposable gloves so you don’t get too greasy. Penetrating fluid works between the bolt and nut threadings to add lubrication and make it easier to unscrew the system. Point the spout of the penetrating fluid directly at the nuts connecting the exhaust pipe to the downpipe attached to your engine. Make sure to coat all of the threadings evenly to make the job easier.  You can buy penetrating fluid from your local hardware or automotive care store. If you don’t have any penetrating fluid, it may be difficult to remove your exhaust system on your own. If your exhaust system is made up of multiple pieces, then look for bolts where the pieces connect to one another. Spray those with your penetrating fluid as well so you can remove each of the pieces separately. Start where your exhaust pipe connects to the engine at the front of your vehicle. Choose a ratchet bit that matches the size of the nuts holding the exhaust system to your vehicle. Place the end of the ratchet over the nut you’re loosening and turn it counterclockwise. Apply firm pressure as you rotate the nut since it may be stuck or locked in tightly. Continue unscrewing the rest of the nuts if the pieces of your exhaust system are held together by other bolts or clamps. Use a ratchet with a long handle so you can get more leverage while you’re disconnecting the old exhaust system. Look near the top of the pipe along its entire length to find the metal pins that extend up and into rubber rings on your vehicle’s body. Support the exhaust pipe with your nondominant hand as you slide the metal pin out from the rubber. Slowly and carefully take the other pins off so the exhaust system comes loose from the body of your vehicle.  If you have trouble pulling the metal pins off of the rings, try lubricating them with soapy water to help them slide out more easily. Don’t let the exhaust pipe drop since it could be heavy and it may hurt you or damage other components under your vehicle. Slowly take the exhaust system from the catalytic converter to the tailpipe and lower it to the ground. Carefully remove the system out from underneath the vehicle so it’s out of the way while you’re working. You can either throw the old exhaust system away or you can try to sell the parts if they’re in usable condition. Do not drive your vehicle while you have the exhaust system removed since it may be illegal in your area and you will release harmful fumes.
