### **Pros and Cons of buying a Starting Line MN/KB84 Silencer for the 2019 Polaris 850 Pro-RMK 163 NE**

#### **Pros**

1. **Reduced Noise Emissions** The primary benefit of a silencer is the significant reduction in exhaust noise, making the bike quieter during operation. This is particularly useful in residential areas, urban environments, or when riding in noise-sensitive zones where excessive engine noise could lead to complaints or legal issues.

2. **Improved Sound Quality** Many riders appreciate the deeper, more refined exhaust note that a quality silencer provides. The MN/KB84 is designed to enhance the natural tone of the engine while suppressing harsh frequencies.

3. **Compliance with Local Regulations** Some regions have strict noise ordinances. Installing an EPA-certified or compliant silencer (if applicable) can help avoid fines or registration issues, though the MN/KB84 s legality depends on local laws always verify before purchasing.

4. **Potential Performance Benefits** Some aftermarket silencers, including the MN/KB84, are designed to improve exhaust flow, which can contribute to better engine efficiency and slight power gains, though the impact is usually modest.

5. **Aesthetic Appeal** A well-designed silencer can enhance the bike s appearance, giving it a more aggressive or sporty look. The MN/KB84 has a sleek, modern design that complements the 850 Pro-RMK s styling.

6. **Durability and Quality** Starting Line is a reputable brand known for high-quality manufacturing. The MN/KB84 is constructed with materials designed to withstand the demands of off-road use, including corrosion resistance and robust construction.

7. **Ease of Installation** The MN/KB84 is designed to be a drop-in replacement for the stock exhaust, which simplifies installation. Many riders report that it can be fitted with basic tools and minimal effort, though professional installation is recommended for optimal results.

8. **Compatibility with Other Mods** If you plan to add other exhaust components (e.g., headers, mufflers, or cat-back systems), the MN/KB84 can serve as a solid foundation for further customization.

#### **Cons**

1. **Potential Legal Issues** The biggest drawback is the risk of non-compliance with emissions and noise regulations. While the MN/KB84 is a legal silencer in many areas, some jurisdictions may still restrict aftermarket exhaust modifications, especially if they alter the bike s original sound signature. Always check local laws before purchasing.

2. **Cost** A quality silencer like the MN/KB84 is an investment. Prices can range from $300 to $500 or more, depending on the retailer and any additional accessories (e.g., mounting hardware, gaskets). This is a significant expense for a single component.

3. **Weight** Silencers, by nature, add weight to the exhaust system. While the MN/KB84 is not excessively heavy, the added mass may slightly affect handling, particularly in aggressive off-road riding conditions.

4. **Maintenance Requirements** Off-road bikes accumulate dirt, mud, and debris, which can clog or damage a silencer over time. The MN/KB84 may require occasional cleaning or inspection to maintain optimal performance, especially if used heavily in rough terrain.

5. **Potential Power Loss** While some silencers improve exhaust flow, others can restrict it, leading to a minor loss of power or torque. The MN/KB84 is generally well-regarded for its flow characteristics, but individual results may vary based on installation quality and other modifications.

6. **Resale Value Impact** Aftermarket exhaust modifications can sometimes reduce a bike s resale value, as some buyers prefer stock or factory-approved components. However, this is subjective and depends on the market and buyer preferences.

7. **Installation Challenges** While the MN/KB84 is designed for ease of installation, improper fitting can lead to leaks, rattling, or even damage to the exhaust system. Riders without mechanical experience may struggle with alignment or sealing, potentially requiring professional help.

8. **Sound Profile Trade-Off** While the MN/KB84 reduces noise, it may not provide the aggressive, high-revving tone that some riders prefer. If you enjoy a louder, more sporty exhaust note, a different aftermarket system (e.g., a straight-pipe or high-flow muffler) might be more suitable.

---

### **Conclusion**

The **Starting Line MN/KB84 silencer** is an excellent choice for riders of the 2019 Polaris 850 Pro-RMK 163 NE who prioritize noise reduction, improved exhaust tone, and a high-quality aftermarket component. It offers a balance of performance, durability, and aesthetic appeal while being relatively straightforward to install. However, potential buyers must carefully consider legal restrictions, budget constraints, and the bike s intended use.

For riders who frequently operate in noise-sensitive areas or seek a quieter, more refined riding experience, the MN/KB84 is a worthwhile upgrade. Conversely, those who prioritize raw power, aggressive sound, or plan to race may find it less ideal and could explore alternative exhaust systems.

### **Recommendation**

If you are certain that the MN/KB84 complies with local laws and regulations, and you value a quieter, more polished exhaust note without sacrificing performance, **proceed with the purchase**. Ensure you have the necessary tools for installation or consult a professional to avoid issues. Pair it with high-quality gaskets and mounting hardware to maximize durability.

For riders unsure about legalities or those who prefer a louder exhaust, consider alternatives like a **cat-back system** or **high-flow muffler** that better suits your sound preferences. Always verify compliance with your state or country s emissions and noise laws before modifying your bike s exhaust system.
