The **SPI Tailpipe Gasket (Part #4349-S678539-29)** is a precision-engineered aftermarket component designed specifically for the **2007 Ski-Doo MX 800**, ensuring a secure and leak-proof seal between the exhaust system and the engine s tailpipe assembly. Crafted from high-temperature-resistant **silicon rubber**, this gasket features a **51 -inch inner diameter (I.D.)** and a **64-inch outer diameter (O.D.)**, perfectly contoured to match the exact dimensions of the Ski-Doo s exhaust manifold and tailpipe interface. The gasket s **16/5-inch thickness** provides optimal compression and flexibility, accommodating minor engine vibrations and thermal expansion without compromising integrity. Engineered with a **smooth, non-abrasive surface**, this gasket minimizes the risk of exhaust gas leaks, which could lead to reduced performance, increased emissions, or even engine damage over time. Ideal for both **OEM replacement** and **custom exhaust upgrades**, this gasket is compatible with a range of aftermarket tailpipes and mufflers, making it a versatile choice for riders looking to enhance their Ski-Doo s exhaust system while maintaining factory-level reliability. Its durable construction ensures longevity, even under the demanding conditions of off-road riding, and its easy installation requiring only standard tools and a bit of silicone-based grease for optimal adhesion makes it a hassle-free solution for maintenance-conscious enthusiasts. Whether you're performing routine upkeep or upgrading your Ski-Doo s exhaust setup, this SPI gasket delivers the precision and performance you need to keep your engine running smoothly.

### **Pros and Cons of buying a OEM SPI Tailpipe Gasket (Part #4349-S678539-29) for a 2007 Ski-Doo MX 800**

#### **Pros:**

1. **OEM Quality and Fit** This is an original equipment manufacturer (OEM) part, meaning it is designed specifically for your Ski-Doo MX 800. It should fit perfectly without modifications, reducing the risk of leaks or improper sealing.

2. **Reliability** SPI (a division of **Suzuki Power Sports**) is a trusted brand in the snowmobile industry, known for producing durable aftermarket and OEM components. The gasket is built to withstand the heat and pressure of exhaust gases, reducing the likelihood of premature failure.

3. **Compatibility with Stock Setup** Since this is the exact gasket used in the factory installation, it will work seamlessly with your existing tailpipe, exhaust system, and engine setup. No additional modifications or adapters should be required.

4. **Long-Term Durability** High-quality gaskets like this one are typically made from heat-resistant materials (such as silicone or fiber-reinforced compounds) that resist warping, cracking, or degradation over time, especially in cold climates.

5. **Ease of Installation** Being an OEM part, it should be straightforward to install, especially if you have basic mechanical experience. Most users report that replacing a tailpipe gasket takes less than an hour with the right tools.

6. **Prevents Exhaust Leaks** A failing gasket can cause exhaust leaks, which not only reduce performance but also pose safety risks (carbon monoxide poisoning) and environmental concerns. Replacing it ensures a tight seal.

7. **Maintenance-Friendly** Since this is a common wear item, it s a relatively inexpensive part to replace proactively rather than waiting for a catastrophic failure (e.g., a blown gasket causing exhaust damage).

#### **Cons:**

1. **Cost** While not excessively expensive, it is a specialized part, and purchasing it directly from SPI or an authorized dealer may be pricier than generic aftermarket alternatives. Prices typically range between **$20 $40**, depending on the source.

2. **Limited Availability Outside Official Channels** Unlike universal gaskets, this part may not be readily available at local snowmobile shops or online marketplaces unless they carry SPI parts. You may need to order it online, which could introduce shipping delays.

3. **Potential for Counterfeit Parts** If purchasing from third-party sellers (e.g., eBay, Amazon, or random online stores), there is a risk of receiving a **counterfeit or low-quality replica**. Always verify the seller s reputation and check for authenticity (e.g., SPI s official website or authorized dealers).

4. **Requires Basic Mechanical Skill** While simple, replacing a tailpipe gasket involves working with exhaust components, which may expose you to heat. If you re not comfortable with basic tools (socket wrenches, torque wrench, gasket maker), you may need to pay a mechanic ( $50 $100 labor).

5. **May Need Cleaning or Replacement of Adjacent Parts** If the gasket was leaking for an extended period, the mating surfaces (flanges on the tailpipe and exhaust) could develop corrosion or carbon buildup. You may need to clean them thoroughly before reinstalling the new gasket.

6. **Not a "One-Size-Fits-All" Solution** While this gasket is specific to the 2007 MX 800, slight variations in exhaust setups (e.g., aftermarket upgrades) could require additional adapters or modifications. Always double-check compatibility if your bike has been modified.

### **Conclusion**

The **SPI tailpipe gasket (4349-S678539-29)** is an excellent choice for maintaining or restoring the integrity of your 2007 Ski-Doo MX 800 s exhaust system. Its **OEM quality, reliability, and ease of installation** make it a practical investment for both performance and safety. However, the **potential for counterfeit parts, limited availability, and the need for basic mechanical skill** are minor drawbacks that can be mitigated with careful purchasing and preparation.

If you re experiencing **exhaust leaks, unusual noises, or reduced performance**, replacing this gasket is a cost-effective preventive measure. For those uncomfortable with DIY repairs, a mechanic can handle the job efficiently.

### **Recommendation**

- **Buy from an authorized source** (SPI s official website, Ski-Doo dealerships, or reputable aftermarket parts suppliers like **SnowmobileParts.com** or **Ski-Doo Outlet**) to avoid counterfeit parts.

- **Inspect the mating surfaces** before installation clean them with a wire brush and gasket scraper if needed.

- **Use a high-quality gasket sealant** (e.g., Permatex 24000 or CRC Gasket Maker) to ensure a perfect seal.

- **Torque the bolts to specification** (typically **18 22 ft-lbs** for Ski-Doo exhaust components) to prevent overtightening or loosening over time.

- **Consider a full exhaust system inspection** if the gasket failure is part of a larger issue (e.g., cracked tailpipe, worn-out hangers).

**Final Verdict:** This is a **highly recommended replacement part** for your 2007 Ski-Doo MX 800, provided you source it responsibly and perform the installation correctly. It s a small but critical component that contributes to both performance and safety.
