Installing a catback exhaust can be a bit of a challenge but you can do it at home by following a few steps. It is advisable to have another individual with you to assist with the installation.
For the installation, you need the following:
- Jack stands
- Floor jack
- If you are wondering how to install a catback exhaust, the first thing you should do is to take some safety precautions before you begin the installation. It will take quite a while to install the exhaust. You need to have some safety glasses and work gloves to protect yourself.
- Once you are well protected, you can begin by positioning your car appropriately. Park your car in an open place to allow you to get as much space as you require for the job. Set the parking brake and make sure the car is in neutral. Use a floor jack to elevate the rear of your vehicle and use the jack stands to hold it up safely. Elevation is essential because it creates the space you need to access the car’s exhaust.
- The next step is to remove the isolator. Rubber isolators are usually used to connect the chassis and tailpipes. Use the WD-40 to coat the isolators and then push them using the screwdriver. The person who is assisting you should be twisting the tailpipe out at this point. This allows you to create a push and pull motion that will make it easy for the lubricant to get in and loosen the isolators.
- When the isolator is out, the next step is to cutting the tailpipes. Use the hacksaw to do this. Begin from the muffler and cut the pipes at precisely 2 inches. It takes time to cut the tailpipes. Once the cutting is done, you can go ahead and remove the tailpipes.
- Find the muffler pipe once the tailpipes are out. The muffler pipes are usually held in place by flanges close to cats. When you locate the muffler pipes, unbolt them. You can use some WD-40 to loosen the pipes before unbolting them.
- When you remove the muffler pipe, you should go ahead to check if your new flanges are a good fit. You can confirm this by sliding them on the stud and checking to see if their drilled holes match.
- Slide your new muffler above the flange studs. You will have to grip the unit to keep it in place while the person assisting you links the muffler hangers and outlet pipes.
- Use the floor jack to lift the car body. You should ensure the car rear remains on the jack stands while you do this. Lifting the car body offers extra space that you need to slide in the tailpipes around the suspense and maneuver it to ensure it gets into the right position. When this is done, you can lower the car body into its initial position.
- The next step is to line up and tighten each unit. Use the wrench to make sure the flange nuts are secure. This helps to change the clearance between your tailpipes and bumper.
- Once this is complete, you can put in the exhaust clamps. The clamps have to be well secured. Tighten the clamps on both the tailpipe and muffler. You should examine the entire unit to determine if there are any alignment problems. There should be no interference with your tailpipes. The chassis and suspension are always found very near the tailpipes but they should not meet one another.
- If there is no alignment concern, you can remove the jack and get your car back into a normal position. Start your engine and listen to the sound of your catback exhaust to make sure it is functioning as required.
Patience is essential if you are asking how to install a catback exhaust. This is because it can take a few hours to complete the entire process. Make sure you have all the right tools and materials before the installation begins. This will save you a lot of frustration. You should also ensure you purchase the correct replacement parts. By following these steps, you will cut on costs because you do not have to take your car to a mechanic for exhaust installation.
