Review HARLEY DAVIDSON Oem Inch Fishtail Muffler

The **Harley-Davidson 6585595 Fishtail Muffler (Part Number: 65855-95)** is a meticulously engineered exhaust component designed to deliver both unmistakable performance and timeless style to Harley-Davidson motorcycles, particularly those equipped with the iconic Twin Cam or Evolution engines. Crafted from high-quality stainless steel, this muffler features a sleek, aerodynamic **fishtail design**, a signature element that enhances the bike s aggressive yet refined aesthetic while optimizing exhaust flow for improved throttle response and power delivery. The dual-tone finish often a polished stainless steel exterior with a contrasting matte or brushed interior adds a touch of sophistication, ensuring the muffler not only performs flawlessly but also stands out as a statement piece on the bike s exhaust system. Engineered with precision, the 65855-95 muffler incorporates a **high-flow exhaust pipe** that reduces backpressure, allowing the engine to breathe more efficiently, which translates to a deeper, more resonant exhaust note that resonates with the classic Harley-Davidson growl. Whether paired with a full exhaust system or as part of a custom setup, this muffler is built to withstand the rigors of daily riding, offering durability and reliability for both urban commuters and long-distance adventurers. Its seamless integration with Harley-Davidson s aftermarket and OEM systems ensures a hassle-free installation, while its attention to detail from the precise fitment to the attention-grabbing design makes it a must-have upgrade for enthusiasts seeking both power and personality in their ride.

### Pros and Cons of buying a Harley-Davidson 6585595 Fishtail Muffler (Part Number: 65855-95)

1. **Authentic Harley-Davidson Fit and Finish** This is an OEM (Original Equipment Manufacturer) part, meaning it is designed to match the exact specifications of Harley-Davidson motorcycles, ensuring a seamless fit without modifications. The build quality aligns with Harley s reputation for durability and craftsmanship.

2. **Improved Sound and Aesthetics** The fishtail muffler is a classic Harley design, known for its distinctive, aggressive exhaust note. It enhances the motorcycle s retro or custom look, appealing to riders who prefer a traditional or modified aesthetic over modern, smoother-sounding systems.

3. **Compatibility with Classic and Custom Builds** This muffler is often used in projects where riders want to restore or modify their bikes to resemble older Harley models (e.g., 1960s 1980s). It pairs well with other retro parts like chrome exhaust headers, single-disc brakes, and vintage-style fuel tanks.

4. **Durability and Longevity** As an OEM part, it is built to withstand the rigors of daily riding, provided it is properly maintained. Harley-Davidson components are generally robust, though wear over time is inevitable with any exhaust system.

5. **Ease of Installation** Since it is an original part, finding installation guides, tutorials, and support from Harley dealerships or mechanics is straightforward. It typically requires basic tools and can be installed in a few hours with the right expertise.

6. **Resale Value for Classic/Modified Bikes** If you plan to sell or trade in your bike later, keeping OEM or high-quality aftermarket parts like this can preserve or even increase the bike s value, especially in the custom or classic Harley market.

7. **Sound Customization Options** While the stock fishtail muffler has a loud, growling tone, it can be paired with other aftermarket components (e.g., headers, mid-pipes, or baffle deletions) to further customize the exhaust note to your preference.

---

1. **Loud and Aggressive Sound** The fishtail muffler is notoriously loud, often exceeding legal noise limits in many regions. This can lead to fines, complaints from neighbors, or restrictions on where you can ride. If you plan to ride on public roads frequently, you may need to pair it with a secondary muffler or baffle to comply with local laws.

2. **Poor Fuel Efficiency** The unrestricted exhaust system contributes to higher backpressure, which can reduce engine efficiency and slightly decrease fuel economy. This is a trade-off for riders prioritizing sound over performance.

3. **Weight** Fishtail mufflers are heavier than some modern or aftermarket alternatives, which can slightly affect handling and acceleration, especially on sportier or lighter bikes.

4. **Maintenance Requirements** Like any exhaust system, this muffler will require periodic inspections for rust, leaks, or damage, particularly if you ride in wet or corrosive environments. Harley s stainless steel mufflers are durable but not immune to wear.

5. **Limited Modern Performance Benefits** While the fishtail design is iconic, it does not offer the same flow or performance advantages as modern, high-flow exhaust systems. If your primary goal is power or efficiency, a different aftermarket system might be more beneficial.

6. **Cost of Replacement Parts** If the muffler fails or is damaged, replacing it can be expensive, especially if you need to buy additional components (e.g., gaskets, hangers, or clamps) to ensure a proper fit.

7. **Potential for Vibration** Depending on your bike s suspension and exhaust hangers, a fishtail muffler can introduce additional vibration, which may require adjustments to the exhaust system or suspension to mitigate.

8. **Aesthetic Polarization** While many riders love the fishtail look, others may find it outdated or overly aggressive. If you re building a bike for a specific style (e.g., modern cruiser or sport), this part may not align with your vision.

The Harley-Davidson 6585595 fishtail muffler is a high-quality, authentic choice for riders who prioritize classic aesthetics, a distinctive exhaust note, and OEM reliability. It is ideal for:

- Restoring or modifying bikes to a vintage Harley look.

- Riders who enjoy the loud, growling sound and don t mind potential legal or noise-related challenges.

- Those who value the brand s heritage and don t mind the trade-offs in fuel efficiency or weight.

- Riders who need to comply with strict noise laws without modifications.

- Those seeking improved performance or fuel efficiency.

- People who prefer a quieter, more modern exhaust tone.

---

If you are certain about the fishtail design and can accommodate its loudness (or are willing to add a secondary muffler for compliance), purchasing this OEM part is a solid investment. Ensure you:

1. Check local noise regulations before installation.

2. Consider pairing it with a high-quality exhaust hanger system to reduce vibration.

3. Budget for potential future maintenance or replacement costs.

4. Explore aftermarket alternatives (e.g., baffled fishtail mufflers or modern high-flow systems) if you want a balance between sound and legality.

For most stock Harley-Davidson bikes, this muffler will look and sound fantastic, but weigh the pros and cons carefully against your riding habits and preferences. If you re unsure, consult with a Harley mechanic or fellow riders in the custom community for tailored advice.
