Get ready to learn about improved horsepower, torque, and sound. Let’s get started!
What Is a Big Gun Slip-on Exhaust?
A slip-on exhaust is a type of aftermarket exhaust system that replaces the rear section of your ATV or UTV’s exhaust. Unlike a full exhaust system, which replaces the entire exhaust from the engine manifold back, a slip-on system is designed to be easier to install and more budget-friendly. The ‘slip-on’ name comes from how it attaches to your existing exhaust header pipe. You simply slide the new muffler onto the existing pipe and secure it with clamps.
Big Gun is a well-regarded manufacturer in the powersports industry, known for producing high-quality exhaust systems for a wide range of ATVs and UTVs. Their slip-on exhausts are designed to improve performance, enhance the sound, and often provide a more stylish look compared to the stock exhaust.
Key Components of a Big Gun Slip-on Exhaust
While the exact components can vary slightly depending on the specific model and your ATV or UTV, a typical Big Gun slip-on exhaust kit includes:
- Muffler: This is the main component, responsible for channeling exhaust gases and reducing noise. Big Gun mufflers are often made from durable materials like stainless steel or aluminum.
- Mid-pipe (if applicable): Some slip-on systems include a mid-pipe that connects the muffler to the existing header pipe. This can improve exhaust flow.
- Clamps and Hardware: All necessary clamps, bolts, and hardware for installation are usually included.
- Instructions: Detailed instructions to guide you through the installation process.
Materials Used in Big Gun Slip-on Exhausts
The materials used in a Big Gun slip-on exhaust play a significant role in its durability, performance, and appearance. Common materials include:
- Stainless Steel: Known for its excellent corrosion resistance and strength. Stainless steel mufflers can withstand harsh environments and offer a long lifespan.
- Aluminum: Lighter than stainless steel, aluminum mufflers can contribute to weight savings. They also often come with a more stylish finish.
- Carbon Fiber (on some models): Carbon fiber is extremely lightweight and offers a high-performance look. It’s often used for end caps or the entire muffler body on premium models.
- Packing Material: High-temperature packing material inside the muffler absorbs sound and helps to regulate exhaust flow.
Benefits of Installing a Big Gun Slip-on Exhaust on Your Sportsman
Upgrading to a Big Gun slip-on exhaust can provide several advantages for your Polaris Sportsman ATV or UTV. These benefits can significantly enhance your riding experience.
Increased Horsepower and Torque
One of the primary benefits of an aftermarket exhaust system is improved performance. Big Gun slip-on exhausts are designed to optimize exhaust flow, which can lead to gains in both horsepower and torque. This means your Sportsman will accelerate quicker, climb hills more easily, and have more power on demand.
The improved exhaust flow allows the engine to breathe more efficiently. This results in better combustion and increased power output. The specific gains will vary depending on the engine size, the model of the exhaust, and any other modifications you’ve made to your ATV or UTV.
Enhanced Sound
Stock exhaust systems are often designed to be quiet, which can sometimes result in a rather muted engine sound. A Big Gun slip-on exhaust will typically provide a deeper, more aggressive exhaust note. This can make your ATV or UTV sound more powerful and enjoyable to ride.
The sound level of Big Gun exhausts is usually within a reasonable range, often balancing performance with noise control. However, it’s always a good idea to check local noise regulations to ensure compliance. (See Also: Won Hundred Willow Slip On Sneakers )
Improved Aesthetics
Beyond performance, a Big Gun slip-on exhaust can significantly enhance the appearance of your Sportsman. The aftermarket exhaust often has a more stylish design than the factory exhaust, adding a touch of personalization to your machine. Big Gun offers various finishes and styles, allowing you to choose an exhaust that complements your ATV or UTV’s look.
The upgraded exhaust can give your Sportsman a more aggressive and modern appearance, making it stand out from the crowd.
Weight Reduction (potentially)
In some cases, a Big Gun slip-on exhaust can result in a slight weight reduction compared to the stock exhaust. This is particularly true if the aftermarket exhaust is made from lighter materials like aluminum or carbon fiber. While the weight savings may not be substantial on their own, they can contribute to overall performance improvements.
Reducing weight can improve acceleration, handling, and overall agility, especially in demanding off-road conditions.
Compatibility with Polaris Sportsman Models
Big Gun slip-on exhausts are designed to fit a wide range of Polaris Sportsman ATV and UTV models. However, it’s crucial to ensure that the exhaust you choose is specifically designed for your machine’s year, engine size, and model. Using an incompatible exhaust can lead to poor performance, installation difficulties, or even damage to your ATV or UTV.
Common Sportsman Models Compatible with Big Gun Exhausts
Big Gun offers exhaust systems for many popular Sportsman models, including:
- Sportsman 450
- Sportsman 570
- Sportsman 850
- Sportsman 1000
- Sportsman XP 1000
Always double-check the product description and compatibility information on the Big Gun website or from the retailer before making a purchase. This will help to confirm that the exhaust is a perfect fit for your specific model.
How to Determine the Right Fit
To ensure a proper fit, you’ll need to know your Sportsman’s year, engine size (e.g., 570cc, 850cc, 1000cc), and specific model (e.g., Sportsman XP 1000). You can find this information on your ATV or UTV’s registration documents, the manufacturer’s label, or in your owner’s manual.
Once you have this information, you can use the Big Gun website or a retailer’s website to search for compatible exhaust systems. They typically have a vehicle selector tool that allows you to enter your ATV or UTV’s details and find the right exhaust for your machine. You can also contact Big Gun directly or a trusted powersports dealer for assistance.

You might need penetrating oil to help loosen stubborn bolts. Carefully remove the stock muffler from the ATV or UTV.
Step 3: Install the Big Gun Slip-On Exhaust. Slide the Big Gun muffler onto the existing header pipe. Align the muffler with the mounting points on the frame. Install the provided clamps and hardware to secure the muffler to the header pipe and frame. Ensure that the muffler is properly aligned and that all connections are tight but not over-tightened.
Step 4: Tighten the Hardware. Use your socket set or torque wrench to tighten all bolts and clamps to the manufacturer’s recommended torque specifications. Refer to the Big Gun’s installation instructions for the correct torque values. Ensure that all connections are secure to prevent exhaust leaks.
Step 5: Inspect and Test. Reconnect the negative terminal of the battery. Start the engine and listen for any exhaust leaks. Check for any unusual noises or vibrations. Let the engine run for a few minutes to allow the exhaust to heat up. Once the engine is warm, check all connections again to ensure that everything is still secure.
Step 6: Final Touches. Clean up any spills or debris. Inspect the installation to make sure everything looks neat and professional. Take your Sportsman for a test ride to evaluate the performance and sound of the new exhaust.

Cleaning and Maintenance
Cleaning: Regularly clean your Big Gun exhaust to remove dirt, mud, and debris. Use a mild soap and water solution and a soft cloth or sponge. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish. Rinse the exhaust thoroughly with clean water and dry it completely.
