How to Install Exhaust Downpipes: A Comprehensive Guide
Downpipes are an essential component of the exhaust system of a vehicle, as they help to remove the harmful exhaust fumes from the engine and prevent the engine from overheating. In this guide, we will go through the process of installing exhaust system downpipes, step by step, so that you can easily upgrade your vehicle and improve its performance.
Why Install Exhaust System Downpipes
There are several reasons why you might want to install exhaust system downpipes on your vehicle, including:
Improved Performance: Downpipes help to increase the flow of exhaust fumes from the engine, which in turn can improve engine performance and power.
Better Sound: A well-designed downpipe can also enhance the sound of your vehicle's exhaust, making it more aggressive and sportier.
Increased Reliability: By reducing backpressure in the exhaust system, downpipes can increase the reliability of your vehicle's engine, as it is under less stress and runs cooler.
Reduced Weight: Some aftermarket downpipes are made of lightweight materials, such as stainless steel or titanium, which can help to reduce the weight of your vehicle and improve handling.
Types of Exhaust System Downpipes
There are two main types of exhaust system downpipes: cat less and catted. Cat less downpipes are designed to replace the catalytic converter and are typically used for racing or off-road purposes, as they do not comply with emissions regulations. Catted downpipes, on the other hand, include a high-flow catalytic converter and are designed for street use, as they meet emissions regulations.
Tools and Equipment Needed
Before you start the installation process, it is important to gather the right tools and equipment. Here is a list of what you will need:
- Jack and jack stands
- Socket set
- Wrench set
- Exhaust hanger pliers
- Exhaust paste or high-temperature silicone sealant
- New gaskets
Step-by-Step Guide to Installing Exhaust System Downpipes
Here is a step-by-step guide to installing exhaust system downpipes:
Lift the Vehicle: Start by lifting the vehicle using a jack and jack stands. Make sure that the vehicle is securely supported before you begin the installation process.
Remove the Stock Exhaust System: Using a socket set and wrench set, remove the stock exhaust system from the vehicle. Make sure to take your time and label each component as you remove it to make re-installation easier.
Install the Downpipes: Once the stock exhaust system has been removed, place the new downpipes into position and secure them using the provided hardware. Make sure to use exhaust paste or high-temperature silicone sealant to seal the joints between the downpipes and the engine.
Re-Install the Stock Exhaust System: Using the new gaskets, re-install the stock exhaust system onto the vehicle, making sure to tighten all bolts and nuts to the manufacturer's specifications.
Test the System: Start the vehicle and listen for any leaks or rattles. If everything sounds good, take the vehicle for a test drive to make sure that the downpipes are properly installed and functioning as intended.
Installing exhaust system downpipes is a relatively straightforward process that can be done with basic automotive tools and a little bit of know-how. With the right equipment and a little patience, you can upgrade your vehicle and enjoy improved performance, better sound, increased reliability, and reduced weight. If you're not confident in your ability to install the downpipes yourself, it is always a good idea to seek the help of a professional mechanic to ensure that the job is done correctly.
