Review HONDA 78-79 Twinstar 185 Left/right Exhaust Hader Pipe System And Mufflers fits CM185T

The **Honda 18300-419-777 78-79 CM185T TwinStar 185cc Exhaust Header Pipe Mufflers** is a meticulously engineered aftermarket upgrade designed to enhance both the performance and aesthetic appeal of Honda s iconic 185cc TwinStar engine, found in models like the 1978-1979 CB185T. These exhaust components are crafted to deliver a refined blend of improved throttle response, deeper engine breathing, and a more engaging exhaust note, all while maintaining the classic charm of the original design. The header pipes are precision-machined from high-quality stainless steel, ensuring durability and resistance to corrosion, even under the demanding conditions of frequent riding or off-road use. The mufflers are thoughtfully tuned to produce a balanced exhaust tone rich yet controlled without sacrificing the signature TwinStar growl that enthusiasts cherish. This upgrade is particularly well-suited for riders seeking a subtle yet noticeable enhancement in their bike s performance, as the optimized exhaust flow reduces backpressure, allowing the engine to breathe more efficiently and unlock a modest increase in power and torque. Beyond performance, the new exhaust system also introduces a sleek, modern aesthetic that complements the retro styling of the CB185T, with a polished finish that stands out against the bike s original components. Whether you re a purist looking to preserve the classic feel while gaining a performance edge or a customizer aiming to refresh the bike s look, these mufflers and header pipes offer a seamless integration that elevates both function and form. Installation is straightforward, thanks to the compatible mounting points and straightforward design, making it an accessible project for DIYers or a quick job for professional mechanics. For riders of the 185cc TwinStar, this exhaust system is more than just an accessory it s a carefully crafted solution to breathe new life into an already legendary engine.

### **Pros and Cons of buying a Honda 18300-419-777 (78-79 cm) TwinStar 185cc Left/Right Exhaust Header Pipe Mufflers**

#### **Pros:**

1. **Enhanced Performance** These exhaust headers and mufflers are designed to improve airflow, reducing backpressure and allowing the engine to breathe more efficiently. This can lead to better throttle response and slight power gains, especially noticeable in acceleration.

2. **Improved Sound** The TwinStar exhaust system is known for producing a deeper, more aggressive tone compared to stock Honda exhausts. This is appealing for riders who want a sportier or more distinctive sound without excessive noise levels.

3. **Durability and Quality** Honda s aftermarket parts, particularly those from the TwinStar line, are generally well-built with high-quality materials. The stainless steel construction ensures resistance to rust and corrosion, making them suitable for long-term use.

4. **Compatibility** These exhaust components are specifically designed for the Honda 185cc models (such as the CB180T, CB185T, or similar), ensuring a proper fit without modifications. The left/right configuration simplifies installation, as they are pre-matched for the bike s exhaust layout.

5. **Ease of Installation** The headers and mufflers are designed for straightforward installation, often requiring only basic tools. Many riders report being able to complete the job in under an hour, especially if they have some mechanical experience.

6. **Aesthetic Appeal** The TwinStar exhaust system has a sleek, modern look that enhances the bike s appearance. The polished or matte finish options (depending on the model) can give the bike a more customized and premium feel.

7. **Warranty and Support** Honda s aftermarket parts typically come with a warranty (usually 1-2 years), providing some assurance against manufacturing defects. Additionally, Honda dealerships and authorized service centers can assist with installation or troubleshooting.

8. **Legal Compliance (In Many Regions)** While exhaust modifications can sometimes raise legal concerns, the TwinStar system is often designed to meet noise regulations in many countries (though always verify local laws before installing).

---

#### **Cons:**

1. **Cost** These exhaust components are not cheap, especially when purchased as a full set (headers mufflers). The price point may be a significant investment for riders on a budget, particularly if they are upgrading from stock.

2. **Noise Levels** While the TwinStar exhaust is louder than stock, it may still exceed legal noise limits in some regions. Riders should check local regulations to avoid fines or registration issues. Some areas require additional muffling or permits for modified exhausts.

3. **Potential Power Increase Concerns** While the power gain is modest, some riders may find that the bike feels slightly more aggressive. This could be a drawback if the rider prefers a quieter, more refined ride. Additionally, some insurance companies may classify the bike as "modified," potentially affecting coverage or premiums.

4. **Installation Challenges** Although the system is designed for ease of installation, some riders may encounter difficulties if they lack mechanical experience. Improper installation could lead to leaks, rattling, or even damage to the exhaust system.

5. **Weight** Exhaust systems, especially stainless steel ones, add weight to the bike. While the difference is minimal, it may slightly affect handling or fuel efficiency in very small ways.

6. **Maintenance Requirements** Stainless steel exhausts are durable but can develop minor corrosion or oxidation over time, especially in humid or salty environments. Regular cleaning and inspection may be necessary to maintain performance and appearance.

7. **Resale Value Impact** Modified exhausts can sometimes deter potential buyers who prefer stock or unmodified bikes. While the TwinStar system is a popular upgrade, it may not appeal to everyone, potentially affecting resale value.

8. **Potential for Aftermarket Parts Incompatibility** If the rider plans to install other aftermarket parts (e.g., a different exhaust system, performance air filter, or carburetor), there may be compatibility concerns. Always ensure that all modifications work together harmoniously.

### **Conclusion**

The **Honda 18300-419-777 TwinStar 185cc exhaust headers and mufflers** are a solid choice for riders looking to enhance their bike s performance, sound, and appearance. The system offers noticeable improvements in airflow and tone while maintaining durability and ease of installation. However, the cost, potential noise issues, and legal considerations must be carefully weighed against the benefits.

If you prioritize a **slight power boost, a deeper exhaust note, and a more aggressive look** without significant drawbacks, this exhaust system is a worthwhile upgrade. That said, if you are on a tight budget, prefer a quieter ride, or plan to keep the bike stock for resale, you may want to reconsider or opt for a more budget-friendly alternative.

**Buy if:**

- You want a **high-quality, Honda-branded exhaust system** that improves performance and sound.

- You are comfortable with the **cost and potential noise implications** in your region.

- If noise is a concern, consider a **milder exhaust upgrade** or a **catalytic converter-compliant system**.

- Always **check local regulations** before installing any exhaust modifications to avoid legal issues.
