Review STARTING LINE PRODUCTS Exhaust Flange Grafoil Seal twin Pipe Arctic Cat fits TWIN 2013

The **2013 Arctic Cat 2104-S746049-34 Exhaust Flange Grafoil Seal for Twin-Pipe Applications** is a precision-engineered aftermarket component designed to ensure a secure, leak-free, and high-performance exhaust system connection on Arctic Cat snowmobiles. Crafted from **high-temperature Grafoil gasket material**, this seal is engineered to withstand the extreme thermal and mechanical stresses of Arctic Cat s twin-pipe exhaust manifolds, providing a reliable barrier against exhaust gases while maintaining optimal engine efficiency. The **custom-fit design** of this flange seal aligns perfectly with the 2013 model s exhaust ports, eliminating gaps that could lead to blow-by, reduced power, or premature wear on the exhaust system. Unlike generic or low-quality seals, this part is built to endure prolonged use in demanding winter conditions, where cold starts, high RPMs, and fluctuating temperatures can compromise inferior materials. Its **reinforced construction** ensures long-lasting durability, reducing the need for frequent replacements and minimizing the risk of exhaust leaks that could introduce harmful fumes into the cabin or compromise engine performance. Whether you're preparing your Arctic Cat for off-season storage or upgrading your exhaust system for improved flow and reliability, this **OEM-quality Grafoil seal** is an essential component for maintaining a tight, efficient seal between the exhaust flange and manifold, keeping your ride running smoothly and powerfully for years to come.

### **Pros and Cons of buying a Starting Line 2104-S746049-34 Exhaust Flange Grafoil Seal for a 2013 Arctic Cat**

1. **Compatibility** This part is specifically designed for the 2013 Arctic Cat engine, ensuring a proper fit without modifications. The part number (2104-S746049-34) is verified for your model, reducing the risk of purchasing an incorrect seal.

2. **High-Quality Material** The seal is made from **Grafoil**, a high-temperature, flexible graphite material that resists warping, cracking, and degradation under extreme heat. This makes it more durable than traditional paper or rubber seals, which can fail prematurely due to heat or vibration.

3. **Prevents Exhaust Leaks** A failing exhaust flange seal can cause **exhaust gas leaks**, leading to reduced engine efficiency, increased emissions, and potential damage to surrounding components. Replacing it with a new Grafoil seal ensures a tight, long-lasting seal.

4. **Easy Installation** The seal is designed to fit standard exhaust flange setups, and many users report that it installs without requiring specialized tools. Proper installation involves cleaning the flange surfaces and applying a thin layer of **high-temperature grease** (like Ceramic Coat or Permatex) to ensure a secure fit.

5. **Cost-Effective Solution** While the price may seem higher than generic seals, Grafoil seals last significantly longer than alternatives, reducing the need for frequent replacements. This can save money in the long run, especially if the seal fails often with cheaper materials.

6. **Reduces Engine Strain** A leaking exhaust flange can cause **backpressure**, forcing the engine to work harder. A properly sealed flange improves exhaust flow, optimizing engine performance and fuel efficiency.

7. **Widely Available & Trusted Brand** Starting Line is a reputable aftermarket parts supplier with a strong reputation for quality. The part is backed by customer reviews and is commonly recommended for Arctic Cat and other small-engine applications.

1. **Potential Overkill for Light Use** If your Arctic Cat is used **minimally** (e.g., occasional yard work or storage), a slightly cheaper seal might suffice. However, Grafoil is still a better long-term choice than paper or rubber, even for low-mileage use.

2. **Requires Proper Installation** If not installed correctly (e.g., uneven pressure, insufficient grease, or debris on the flange), the seal may not perform as expected. Improper installation can lead to premature failure or leaks.

3. **Higher Upfront Cost** Compared to generic or OEM replacement seals, Grafoil seals are more expensive. However, this cost is often justified by their longevity.

4. **Limited Availability of Replacement Parts** While Grafoil seals are durable, if the seal fails after years of use, finding an exact replacement may be easier with Starting Line than with some generic brands.

5. **Heat Sensitivity (Rare but Possible)** While Grafoil is heat-resistant, extreme prolonged exposure to **very high temperatures** (beyond normal operating conditions) could theoretically degrade the material over time. Most Arctic Cat engines, however, operate within safe parameters for this seal.

### **Conclusion & Recommendation**

The **Starting Line 2104-S746049-34 Grafoil exhaust flange seal** is an **excellent choice** for a 2013 Arctic Cat engine. Its **superior durability, heat resistance, and compatibility** make it a reliable upgrade over standard seals. While it may cost more upfront, its **long lifespan and performance benefits** far outweigh the drawbacks for most users.

- **Buy it.** If you re replacing an old or failing exhaust flange seal, this Grafoil seal is the best option for long-term reliability.

- **Ensure proper installation** by cleaning the flange surfaces thoroughly and applying a thin layer of high-temperature grease.

- **Store it properly** if not using the engine for an extended period to prevent seal degradation from moisture or dust.

For most Arctic Cat owners, this is the **best available seal** for the job, and the investment is well justified by its performance and longevity.
