The **Cobra 1171B-1170B 17-24 Harley-Davidson Milwaukee Slip-On Slash Mufflers** are a meticulously engineered aftermarket upgrade designed to transform the exhaust note of Harley-Davidson touring models from the **2017 to 2024 generations**, including the **Touring, Tour Glide, Road Glide, and Street Glide** platforms. Crafted from **high-grade 304 stainless steel**, these mufflers are built to withstand the rigorous demands of daily riding while delivering a bold, aggressive exhaust tone that stands out from stock. The **Slash design** features a **high-flow, dual-chamber construction** with strategically placed **perforated baffles**, allowing for a deeper, more resonant growl that enhances the motorcycle s presence without sacrificing performance. Unlike traditional straight-through mufflers, the Slash configuration introduces a subtle **backpressure effect**, creating a dynamic exhaust pulse that shifts between low-end rumble and high-rev snarl, making every throttle pull more engaging. These mufflers are **easy to install** with a **slip-on design**, requiring no welding or exhaust modifications just a simple bolt-on fitment that pairs seamlessly with the stock headers or aftermarket options. The **sleek, aggressive styling** complements the aggressive aesthetic of modern Harley touring bikes, while the **durable construction** ensures longevity even under heavy use. Whether cruising down the highway or carving through twisty backroads, the **Cobra Slash mufflers** elevate the riding experience with a **distinctive, muscle-car-inspired exhaust tone** that turns heads and turns up the volume on your bike s personality. Perfect for riders who demand both **performance and presence**, these mufflers are a must-have for anyone looking to give their Harley a **custom edge** without the hassle of a full exhaust swap.

### Pros and Cons of buying a Cobra 1171B-1170B 17-24 Harley Touring Milwaukee Slip-On/Slash Mufflers

1. **Sound Quality and Character** These mufflers are designed to enhance the stock Harley-Davidson exhaust note while adding a deeper, more aggressive tone. The Milwaukee Slip-On/Slash configuration provides a balanced sound that retains some of the stock growl but with added power and presence, making it ideal for touring bikes where a slightly louder, more engaging exhaust is desired.

2. **Legal Compliance** The 17-24 series is designed to meet or exceed most state and federal noise regulations in the U.S., including California s stricter laws. This means you can legally ride without worrying about fines or violations, which is particularly important for touring riders who may travel through multiple states.

3. **Durability and Build Quality** Cobra exhaust systems are known for their robust construction, using high-quality materials like stainless steel and heat-treated components. The slip-on design ensures a secure fit without the need for welding, reducing the risk of leaks or damage over time. The Milwaukee series is built to last, even under the demanding conditions of long-distance touring.

4. **Ease of Installation** As slip-on mufflers, these are relatively straightforward to install compared to full exhaust systems. They can often be fitted without the need for professional help, though some basic mechanical skills are recommended. The kit includes all necessary hardware, simplifying the process.

5. **Compatibility** These mufflers are specifically designed for Harley-Davidson touring models from the 17-24 series (e.g., Road Glide, Electra Glide, Tour Glide, etc.), ensuring a perfect fit without modifications. The slip-on design also allows for easy removal if you ever want to revert to stock or switch to another exhaust system.

6. **Aesthetic Appeal** The Milwaukee series features a sleek, aggressive design that complements the aggressive styling of Harley touring bikes. The black or matte finishes (depending on the model) add a modern touch while maintaining a rugged look.

7. **Performance Benefits** While not as extreme as aftermarket performance exhausts, these mufflers provide a slight improvement in backpressure, which can enhance throttle response and engine efficiency. The design is optimized to work well with the stock engine without causing undue stress.

8. **Warranty and Support** Cobra offers a solid warranty (typically 1-2 years) on their exhaust systems, along with customer support for installation questions or issues. This provides peace of mind in case of manufacturing defects or installation problems.

---

1. **Cost** These mufflers are not cheap, typically ranging between $800 and $1,200 depending on the model and whether they include additional components like headers or mid-pipes. For a touring bike, this is a significant investment, especially if you're on a budget.

2. **Sound May Be Too Loud for Some** While the 17-24 series is designed to be legal in most states, some riders may find the sound too aggressive or obnoxious, especially in residential areas or quiet neighborhoods. If you prefer a more subtle exhaust tone, these mufflers may not be ideal.

3. **Weight** Exhaust systems, even slip-on mufflers, add weight to the bike. While the increase is modest, touring riders who prioritize weight savings may find this a minor drawback, though it s unlikely to be a significant issue for most.

4. **Potential for Backpressure Issues** Some riders report that certain slip-on exhausts can cause slight backpressure, which may affect engine performance or fuel efficiency. However, the Cobra 17-24 series is designed to minimize this, and most users do not notice a significant difference from stock.

5. **Installation Complexity** While slip-on mufflers are easier to install than full exhausts, they still require careful handling of the exhaust system, gaskets, and mounting hardware. A mistake during installation (e.g., improper sealing or misalignment) can lead to leaks or rattling, which may require professional attention.

6. **Limited Customization** If you're looking for extreme sound modifications (e.g., deep-throated, high-flow exhausts), these mufflers offer a moderate upgrade rather than a radical change. For riders seeking a more aggressive or performance-oriented exhaust, other brands or full systems may be better suited.

7. **Resale Value Impact** Aftermarket exhausts can sometimes reduce the resale value of a Harley, especially if the bike is being sold as stock or near-stock. However, since these mufflers are legal and well-regarded, the impact may be minimal compared to illegal or overly aggressive exhausts.

8. **Potential for Heat Buildup** Like all exhaust systems, these mufflers generate heat, which can affect nearby components (e.g., fuel lines, brake systems) if not properly routed. Cobra designs account for this, but riders should ensure proper clearance and insulation where necessary.

The Cobra 1171B-1170B 17-24 Harley Touring Milwaukee Slip-On/Slash mufflers are a well-balanced choice for riders who want to enhance their bike s exhaust tone without violating noise laws or compromising performance. They offer a legal, durable, and aesthetically pleasing upgrade that retains some of the stock Harley character while adding depth and aggression. The ease of installation and compatibility with touring models make them a practical option for riders who prioritize sound quality and compliance.

However, the cost is a significant consideration, and the sound may not appeal to those who prefer a quieter or more subtle exhaust. If you re willing to invest in a legal, high-quality exhaust system that improves your bike s sound and appearance without drastic modifications, these mufflers are an excellent choice. For riders seeking more extreme sound or performance gains, a full exhaust system or other brands may be worth exploring.
