### **Pros and Cons of buying a National Slip Exhaust (Model 550-1159) for a 550-1159 Harley-Davidson**

#### **Pros**

1. **Compatibility and Fit**

The National Slip Exhaust (550-1159) is specifically designed for Harley-Davidson engines in the 550cc (550, 883, 114, 1200, and 1340cc) range, including the 1159 Pan America and other touring models. It is engineered to fit seamlessly with the stock exhaust system, ensuring proper alignment and functionality without requiring extensive modifications.

2. **Improved Sound and Tone**

This exhaust system is known for delivering a deeper, more resonant tone compared to the stock exhaust. It enhances the engine s natural sound while maintaining a balanced, aggressive growl that appeals to Harley enthusiasts. The slip-on design allows for better exhaust flow, which can contribute to a more engaging listening experience.

3. **Performance Benefits**

The slip exhaust reduces backpressure, which can lead to slight improvements in throttle response and power delivery. While the gains may not be dramatic, they can contribute to a more responsive ride, especially in low-to-mid RPM ranges. This is particularly noticeable in touring bikes where smooth power delivery is desirable.

4. **Durability and Quality**

National Exhaust is a reputable brand known for manufacturing high-quality exhaust systems. The 550-1159 model is constructed with durable materials, including stainless steel components, which resist corrosion and withstand the rigors of daily riding. The system is designed to last for many miles with proper maintenance.

5. **Ease of Installation**

As a slip-on exhaust, this system is relatively straightforward to install compared to full-length exhausts. It typically requires only basic tools and can be completed in a few hours, making it an attractive option for DIY enthusiasts. Many Harley dealerships and mechanics also offer installation services.

6. **Aesthetic Appeal**

The National Slip Exhaust features a sleek, aggressive design that complements the aggressive styling of Harley-Davidson motorcycles. It adds a sportier look to touring models, making the bike stand out while maintaining a level of sophistication.

7. **Compatibility with Aftermarket Upgrades**

The slip exhaust system can be easily integrated with other aftermarket modifications, such as headers, cat-back exhausts, or performance air filters. This makes it a versatile choice for riders looking to customize their bike over time.

---

#### **Cons**

1. **Limited Sound Customization**

While the National Slip Exhaust enhances the stock tone, it does not offer the same level of sound customization as a full cat-back exhaust system. If you are looking for a drastically different or louder sound, you may need to pair this with a secondary exhaust system or muffler.

2. **Minimal Performance Gains**

The improvements in power and throttle response are modest. For riders seeking significant performance upgrades, a full exhaust system or other modifications (such as headers or a high-flow air intake) may be more beneficial.

3. **Potential for Increased Heat**

The slip exhaust can generate more heat than the stock system, particularly in the slip-on section. This may require additional heat shielding or insulation around the exhaust to protect surrounding components and the rider s legs.

4. **Cost Relative to Stock**

While the National Slip Exhaust is not excessively expensive, it represents a noticeable upgrade over the stock system. For budget-conscious riders, the cost may be a deterrent, especially if they are not prioritizing sound or minor performance improvements.

5. **Installation Considerations**

Although the installation is relatively simple, it does require attention to detail to ensure proper sealing and alignment. Improper installation can lead to leaks, rattling, or even damage to the exhaust system. Riders without mechanical experience may need to seek professional help, which adds to the overall cost.

6. **Potential for Noise Complaints**

While the sound is improved, it may still be louder than the stock exhaust, which could draw attention or lead to complaints from neighbors or in areas with strict noise regulations. Always check local laws regarding motorcycle exhaust noise.

7. **Limited Longevity Compared to Full Exhausts**

Slip exhausts are generally less durable than full-length exhaust systems, particularly in the slip-on section, which is exposed to more stress and heat. Over time, the slip-on may require replacement or maintenance, whereas a full exhaust system might last longer with fewer issues.

---

### **Conclusion**

The National Slip Exhaust (550-1159) is an excellent choice for Harley-Davidson riders seeking a subtle yet noticeable upgrade to their stock exhaust system. It offers improved sound, minor performance benefits, and a sportier appearance without requiring extensive modifications. The ease of installation and durability make it a practical option for both DIY enthusiasts and those who prefer professional installation.

However, it is not a comprehensive performance upgrade, and its sound is limited compared to full exhaust systems. Riders should weigh the pros and cons against their priorities whether it s aesthetics, minor performance gains, or simply a more engaging sound before making a purchase.

---

### **Recommendation**

If you are looking for a straightforward, high-quality exhaust upgrade that enhances the stock tone and provides minor performance benefits without significant modifications, the **National Slip Exhaust (550-1159) is a strong recommendation**. It is particularly well-suited for riders who:

- Want a deeper, more aggressive sound without drastic changes.

- Prefer a relatively easy installation with minimal downtime.

- Are satisfied with modest performance improvements and a sportier look.

For riders seeking more significant sound or performance upgrades, consider pairing this slip exhaust with a full cat-back system or other aftermarket modifications. Always ensure compliance with local noise regulations and consider professional installation if you are unsure about the process.
