### **Pros and Cons of buying a Starting Line 09-116 SLP Performance Muffler for 2015 2025 Polaris 900 RZR (RZR-S, XC)**

1. **Improved Exhaust Flow and Horsepower** The SLP muffler is designed to reduce backpressure, allowing the engine to breathe better. This can lead to a noticeable increase in horsepower and throttle response, especially in stock or lightly modified engines.

2. **Better Sound** The muffler provides a deeper, more aggressive exhaust note compared to the stock unit. It retains some of the stock s growl while adding a more pronounced, sporty tone, which appeals to riders who want a more engaging sound.

3. **Durability and Quality** Starting Line mufflers are known for their robust construction, often featuring high-quality materials like stainless steel and reinforced baffles. This can extend the lifespan of the exhaust system compared to aftermarket knockoffs.

4. **Compatibility** The 09-116 model is specifically designed for the 2015 2025 Polaris 900 RZR lineup, including the RZR-S and XC variants. It should fit without modifications, assuming the frame and exhaust mounting points are standard.

5. **Easier Installation** Many Starting Line mufflers come with gaskets, clamps, and sometimes even mounting hardware, simplifying the installation process compared to some other aftermarket exhaust systems.

6. **Maintains Stock Functionality** Unlike some high-flow exhausts that sacrifice sound or performance, the SLP muffler strikes a balance, offering both power gains and an improved exhaust tone without being overly loud (though it may exceed EPA noise limits in some regions).

7. **Positive Community Reception** Many Polaris RZR owners report good results with Starting Line mufflers, citing improved performance and a satisfying exhaust note without excessive wear on the engine.

1. **Noise Compliance Issues** While the SLP muffler is louder than stock, it may still exceed legal noise limits in some states or countries. Riders should check local regulations before installation, as excessive noise can result in fines or the need for additional sound-deadening modifications.

2. **Potential Backfire Risk** Reducing backpressure can sometimes lead to occasional backfires, especially during hard acceleration or deceleration. This is more common in carbureted engines but can still occur in fuel-injected models.

3. **Cost** Starting Line mufflers are priced higher than stock units, typically ranging between $200 $300 depending on the retailer. This is a significant investment if you re only looking for minor upgrades.

4. **Limited Power Gains for Heavy Mods** If your RZR is already heavily modified (e.g., with a turbo, big bore kit, or aggressive tuning), the SLP muffler may not provide as significant a power increase as you d expect. It s best suited for stock or lightly modified engines.

5. **Installation Complexity** While easier than some exhaust systems, replacing the muffler still requires removing the RZR s undercarriage, disconnecting the stock muffler, and properly sealing the new unit. Those unfamiliar with exhaust work may need professional help.

6. **Potential for Exhaust Leaks** Like any aftermarket exhaust, improper installation or low-quality gaskets can lead to leaks. Ensuring a tight seal is crucial to avoid exhaust fumes entering the cabin or damaging surrounding components.

7. **Resale Impact** If you plan to sell the RZR later, some buyers may prefer stock or quieter exhaust systems. The SLP muffler could deter potential buyers who prioritize noise compliance or stock aesthetics.

### **Conclusion**

The **Starting Line 09-116 SLP Performance Muffler** is a solid choice for Polaris 900 RZR owners looking to enhance exhaust flow, improve horsepower, and enjoy a deeper, more engaging sound without a full exhaust swap. It strikes a balance between performance and practicality, making it ideal for riders who want noticeable upgrades without extreme modifications.

However, it s not without drawbacks primarily noise concerns, potential backfire risks, and the cost of installation. If you re comfortable with a louder exhaust and don t mind checking local noise laws, this muffler is a worthwhile upgrade. For those who prioritize stealth or plan to keep the RZR stock-like, it may not be the best fit.

---

### **Recommendation**

- You want a noticeable power increase and improved exhaust tone.

- Your RZR is stock or lightly modified.

- You re willing to accept a louder exhaust (and check local noise regulations).

- You value durability and quality over minimalist aesthetics.

- You need to comply with strict noise laws (consider a quieter aftermarket muffler or a sound-deadening kit).

- Your RZR is already heavily modified (a full exhaust system may yield better results).

- You prefer a near-stock sound or plan to sell the RZR soon.

For the best results, pair this muffler with a **cat-back exhaust system** or **full exhaust swap** if you re going for maximum performance. Always ensure proper installation to avoid leaks or backfire issues.
