Review BOYESEN Super Stock Reeds carbon Fiber Polaris fits TRAIL BOSS 1990–1993

The Boyesen 8773-B464124 ATV Reeds-Carbon Fiber Kit is a meticulously engineered aftermarket upgrade designed to transform the handling, performance, and aesthetics of your 1990 through 1993 Polaris Trail Boss 350L into a more responsive and visually striking machine. This high-performance kit replaces the stock steel reeds with a lightweight yet ultra-strong carbon fiber assembly, significantly reducing unsprung weight while enhancing rigidity and torsional stiffness. The carbon fiber construction not only delivers superior durability and resistance to fatigue critical for off-road use it also minimizes vibration transfer to the rider, resulting in a smoother, more controlled ride. The precision-machined design ensures a perfect fit with the Trail Boss s suspension system, maintaining optimal alignment and eliminating the flex that can compromise handling on rough terrain. Beyond its mechanical advantages, the carbon fiber reeds offer a sleek, modern aesthetic that elevates the classic Trail Boss s rugged appeal, blending cutting-edge technology with timeless off-road heritage. Whether tackling rocky trails, deep mud, or technical single-track, this kit empowers the 350L with the agility and confidence of a more advanced ATV, making it an ideal choice for riders who demand both performance and precision. Built to withstand the demands of serious off-roading, the Boyesen carbon fiber reeds are a testament to modern engineering s ability to enhance an iconic machine without compromising its legendary reliability.

### Pros and Cons of Buying Boyesen 8773-B464124 ATV Reeds-Carbon Fiber for a 1990-1993 Polaris Trail Boss 350L

1. **Improved Performance** Carbon fiber reeds are designed to enhance airflow and exhaust efficiency, which can increase horsepower and throttle response. This is particularly beneficial for older ATVs like the Polaris Trail Boss 350L, which may have lost some power over time due to wear or stock exhaust restrictions.

2. **Lightweight Construction** Carbon fiber is significantly lighter than traditional steel reeds, reducing overall exhaust system weight. This can improve handling and acceleration, especially on off-road terrain where weight reduction is advantageous.

3. **Durability and Heat Resistance** Carbon fiber reeds are highly resistant to warping and corrosion, making them more durable than some aftermarket steel alternatives. They can withstand high temperatures without losing structural integrity, which is crucial for performance applications.

4. **Aesthetic Appeal** The sleek, modern look of carbon fiber reeds can give your Trail Boss a more aggressive and customized appearance, which may appeal to enthusiasts who prioritize style alongside performance.

5. **Potential for Better Sound** While exhaust tone is subjective, carbon fiber reeds can produce a distinct, sharper exhaust note compared to stock or heavy steel systems. Some riders prefer this sound for its sportier character.

6. **Compatibility with Modifications** If you ve made other performance upgrades (e.g., turbocharging, forced induction, or high-flow intake), carbon fiber reeds can complement these changes by improving exhaust flow and scavenging.

7. **Long-Term Reliability** Boyesen is a reputable brand known for quality manufacturing and customer support. Their carbon fiber reeds are engineered to last, reducing the risk of premature failure compared to cheaper, poorly made alternatives.

---

1. **Cost** Carbon fiber reeds are significantly more expensive than stock or basic aftermarket exhaust components. For a 1990-1993 Trail Boss 350L, which is already an older model, the investment may feel disproportionate unless you re heavily invested in performance upgrades.

2. **Installation Complexity** While not overly difficult, installing carbon fiber reeds may require some mechanical skill, especially if you re unfamiliar with exhaust system modifications. Improper installation (e.g., loose clamps, misaligned flanges) can lead to leaks or damage.

3. **Limited Aftermarket Support** Unlike stock or common steel reeds, carbon fiber reeds may not have as many readily available replacement parts or gaskets. If something goes wrong, sourcing parts could be more challenging.

4. **Potential for Overkill** For a stock or lightly modified Trail Boss 350L, the gains from carbon fiber reeds might be modest. If you re not pushing the engine hard or running forced induction, the performance boost may not justify the cost.

5. **Sound Preferences** Some riders dislike the sharper, more aggressive tone of carbon fiber reeds, preferring the deeper, rumbling sound of stock or heavy steel exhausts. This is subjective, but it s worth considering if you value a specific exhaust note.

6. **Weight Transfer Considerations** While carbon fiber is lighter, the overall impact on handling may be minimal unless you re running other weight-reducing modifications. The Trail Boss 350L is already a robust ATV, so this may not be a major factor.

7. **Resale Value Impact** If you plan to sell the ATV later, heavily customized exhaust systems (especially high-end ones like carbon fiber reeds) might deter buyers who prefer stock or simpler modifications. However, this depends on the buyer s preferences.

The Boyesen 8773-B464124 carbon fiber reeds are an excellent choice if you re looking to **maximize performance, reduce weight, and future-proof your Trail Boss 350L** for more aggressive modifications (e.g., turbocharging or high-flow intakes). They offer tangible benefits in airflow, durability, and aesthetics, making them ideal for riders who prioritize power and precision.

However, if your primary goal is **basic off-road use, cost efficiency, or maintaining a stock-like appearance**, the cost and complexity may not be worth it. For a 1990-1993 Trail Boss 350L, which is already a capable but aging machine, the gains from carbon fiber reeds might be more noticeable if you re running other performance upgrades. If you re happy with stock power or only want subtle improvements, a more affordable aftermarket steel reed or a high-flow muffler could be a better fit.

---

- You re committed to performance upgrades (e.g., turbo, forced induction, or high-flow air intake).

- You want a lightweight, durable exhaust system that enhances throttle response and power.

- You appreciate the aesthetic and sound characteristics of carbon fiber.

- You re willing to invest in a high-quality, long-term solution that complements other mods.

- You re on a tight budget or only want minor improvements.

- You prefer the stock or deeper exhaust tone of steel reeds.

- You plan to sell the ATV soon and want to minimize customization.

- You re unsure about installation or maintenance complexities.

For a 1990-1993 Trail Boss 350L, pairing these reeds with a **high-flow intake, air filter upgrade, or basic turbo kit** (if applicable) would yield the best results. If you re unsure, test-riding or consulting with a local ATV mechanic familiar with carbon fiber exhausts could help confirm whether the upgrade aligns with your riding goals.
