If you’re looking to enhance your vehicle’s power, improve its sound, and boost overall performance, installing a performance exhaust system can be one of the most effective upgrades you can make. Whether you’re after that deep, throaty growl or just a little extra horsepower, this guide will take you step-by-step through the process of installing a performance exhaust system. By the end of this article, you’ll be ready to tackle this exciting project with confidence.
Why Install a Performance Exhaust System?
Before we dive into the nuts and bolts of installation, it’s important to understand why you might want to upgrade to a performance exhaust system. Essentially, performance exhausts are designed to reduce backpressure, allowing for a more efficient flow of exhaust gases. This, in turn, can boost your engine’s horsepower, improve fuel efficiency, and create that iconic sporty sound many enthusiasts love.
If you’re still on the fence, it’s helpful to know that many performance exhaust systems are designed to replace the factory exhaust without too much modification, making this an achievable task even if you’re not a seasoned mechanic. Plus, the pride of upgrading your car with your own hands is worth every minute.
Tools and Products You’ll Need
Before getting started, make sure you have the necessary tools and products at your disposal. This will save time and ensure a smoother installation process. You can find most of these items on Amazon, often with customer reviews that will help you decide which ones are best for you.
Tools:
- Socket wrench set (such as the DEWALT Mechanics Tools Kit and Socket Set, highly rated and popular)
- Ratchet extension
- Penetrating oil (WD-40 is a great option)
- Rubber mallet
- Safety gloves and glasses
- Car jack and jack stands
Products for the Job:
- Performance Exhaust System: Look for a quality cat-back or axle-back exhaust system compatible with your vehicle. The Flowmaster American Thunder Cat-Back Exhaust System is highly rated and widely used for improved sound and performance.
- Exhaust Clamps: You may need some extra exhaust clamps, like these Walker Heavy Duty Steel Exhaust Clamps.
- Exhaust Sealant: Use an exhaust sealant like Permatex Muffler and Tailpipe Sealer to prevent leaks during assembly.
Step 1: Preparation and Safety
The first step to any successful installation is preparation. Make sure your vehicle is parked on a flat, even surface. Safety is paramount, so you’ll want to wear gloves and safety glasses. Use a jack to lift your vehicle and secure it with jack stands. Double-check the stability of the vehicle before crawling underneath it.
Spray the bolts of your existing exhaust system liberally with a penetrating oil like WD-40. Let it sit for about 10 to 15 minutes. This will make it much easier to remove the rusted, stubborn bolts later on.
Step 2: Removing the Old Exhaust System
Now that your vehicle is secure and you’ve let the penetrating oil work its magic, it’s time to remove the stock exhaust system. Most exhaust systems are held together by bolts, so you’ll need a socket wrench and possibly a ratchet extension for some of those hard-to-reach spots.
- Locate the Bolts: Start by locating the bolts that attach the exhaust to the catalytic converter. Use your socket wrench to remove these bolts.
- Disconnect the Hangers: Your exhaust is likely suspended from the undercarriage with rubber hangers. Use a rubber mallet or simply slide the hangers off by hand. These can be a bit tight, but be patient and apply even pressure. You may also use a hanger removal tool to make things easier.
- Remove the Entire System: Once the hangers are off, gently remove the rest of the exhaust system, working your way back towards the muffler. This can be a little unwieldy, so having a friend to help can be very beneficial.
Step 3: Preparing for the New Performance Exhaust
Before installing your new performance exhaust, take a moment to clean the undercarriage where the old system was attached. Check for any leftover rust or debris, as a clean surface will ensure a better fit and a tighter seal.
Step 4: Installing the New Performance Exhaust System
Now comes the exciting part: installing your new performance exhaust! This process will essentially be the reverse of removing the old system. You should begin at the front of the car, attaching the exhaust to the catalytic converter, and work your way back towards the muffler.
- Line Up the System: Begin by aligning the new exhaust system with the existing mounts under your vehicle. Depending on the system you purchased, it may be a direct bolt-on installation or you might need to make slight adjustments.
- Attach the Piping: Start by attaching the pipes closest to the catalytic converter, then move down the line until you reach the muffler. Make sure each section overlaps properly and that the connections are tight.
- Install the Clamps and Hangers: Use exhaust clamps like the Walker Heavy Duty Steel Exhaust Clamps to secure each connection point. Be sure to tighten the clamps securely. If you’re reusing the rubber hangers, slide the new exhaust hangers into place, making sure everything is secure.
- Seal the Connections: Apply exhaust sealant like Permatex Muffler and Tailpipe Sealer around each connection point. This will help prevent leaks and ensure your exhaust system runs efficiently.
Step 5: Double-Check Your Work
Before you lower your car, it’s important to double-check all the connections. Make sure that all bolts are tight and that the exhaust system is not touching any part of the vehicle’s undercarriage. Loose or misplaced exhaust components can lead to annoying rattles or worse, damage to the system.
Step 6: Test the Installation
After you’re satisfied with the installation, lower your car from the jack stands. It’s now time to start your vehicle and check for any leaks. Listen carefully for any odd noises, such as hissing, which could indicate a leak in the system.
You should immediately notice a difference in the exhaust note. It should sound deeper, more refined, and more aggressive depending on the type of exhaust you chose. Also, take your car for a test drive to make sure everything is functioning correctly and that there are no vibrations or unusual sounds.

Tips for Successful Installation
- Take Your Time: Rushing the installation can lead to mistakes. Make sure to follow each step carefully, ensuring a proper fit for each component.
- Have a Friend Help: Exhaust systems can be awkward to handle on your own, especially when aligning sections. Having an extra set of hands makes things much easier.
- Use Penetrating Oil: Rust can make bolts extremely stubborn. Applying penetrating oil beforehand will save you a lot of frustration.
- Use Quality Tools: Quality tools can make all the difference. Investing in a good socket set like the DEWALT Mechanics Tools Kit will not only make your installation easier but also provide you with reliable tools for future projects.
Common Mistakes to Avoid
- Not Tightening Clamps Properly: Loose clamps can cause leaks or even parts of the exhaust to separate. Make sure all connections are tight.
- Skipping the Test Drive: Always take the car for a test drive after installation. This will allow you to notice any issues before hitting the open road.
- Skipping Exhaust Sealant: Using an exhaust sealant around the joints and connections can help prevent leaks. Don’t skip this step—it’s well worth the extra effort.
