Review STARTING LINE PRODUCTS Slp Exhaust Flange Grafoil Seal twin Pipe Polaris Snowmobile fits TWIN SKS 800 2003

The **Starting Line 2251-S746343-91 SLP Exhaust Flange Grafoil Seal for 2003 Polaris 800 SKS** is a precision-engineered aftermarket component designed to enhance both performance and longevity of your Polaris 800 Sport Kits (SKS) by addressing a critical weak point in the stock exhaust system. This high-quality **Grafoil-based seal kit** is specifically crafted to replace the factory exhaust flange gasket, which is notorious for leaking exhaust gases, causing excessive heat buildup, and compromising engine efficiency over time. The seal features a **thick, durable Grafoil composition**, a material renowned for its superior heat resistance, flexibility, and long-lasting adhesion properties, ensuring a tight, leak-proof seal that withstands the extreme temperatures and vibrations inherent in high-performance off-road applications. Unlike generic or low-quality gaskets that may crack, warp, or fail under stress, this seal is engineered to maintain its integrity even under the most demanding riding conditions, from aggressive trail riding to sustained high-speed cruising. Installation is straightforward, requiring only basic tools, and the kit includes all necessary components including the flange itself to ensure a seamless upgrade without the need for additional modifications. By upgrading to this **Starting Line exhaust flange seal**, riders can eliminate exhaust leaks, reduce heat transfer to surrounding components, and restore optimal engine performance, all while extending the lifespan of the exhaust system and improving overall ride quality. Whether you're looking to maintain stock exhaust functionality or prepare for a more extensive exhaust upgrade, this seal is an essential, cost-effective solution that delivers professional-grade results.

### **Pros and Cons of buying a Starting Line 2251-S746343-91 SLP Exhaust Flange Grafoil Seal for a 2003 Polaris 800 SKS**

1. **Compatibility** This part is specifically designed for the 2003 Polaris 800 SKS, ensuring a proper fit without modifications.

2. **High-Quality Seal** The Grafoil material provides a durable, heat-resistant seal that prevents exhaust leaks, which is crucial for maintaining performance and reducing noise.

3. **SLP (Sound Level Performance) Design** The SLP designation suggests that this exhaust flange is engineered to improve exhaust flow while minimizing backpressure, which can enhance engine efficiency.

4. **Easy Installation** As a direct replacement, it should fit standard exhaust systems without requiring extensive modifications, making it a straightforward upgrade.

5. **Reliability** Starting Line is a trusted brand in off-road and ATV parts, known for producing durable components that withstand demanding conditions.

6. **Noise Reduction** A properly sealed exhaust flange helps contain engine noise, which is beneficial for both rider comfort and compliance with noise regulations in some areas.

7. **Prevents Corrosion** The Grafoil seal acts as a barrier against moisture and debris, reducing the risk of rust and exhaust system damage over time.

1. **Cost** Compared to generic or aftermarket alternatives, this part may be more expensive, especially if purchased as part of a full exhaust system upgrade.

2. **Limited Availability** Depending on the retailer, this specific part might not be as widely stocked as universal or OEM alternatives, requiring online ordering or special purchases.

3. **Potential Overkill for Stock Systems** If you re not planning to modify your exhaust system further (e.g., adding a muffler or downpipe), the benefits of this high-performance seal may be minimal.

4. **Installation Skill Required** While the part is designed for easy installation, improper handling (e.g., damaging the Grafoil seal during mounting) could void its effectiveness or require replacement.

5. **Compatibility with Aftermarket Exhausts** If you re running a non-OEM exhaust system, this flange may not fit perfectly, requiring additional adapters or modifications.

6. **Wear Over Time** Like all seals, Grafoil can degrade with extreme heat or prolonged use, potentially requiring eventual replacement, though it is generally long-lasting.
