Review MBRP Series Performance Exhaust Polaris Pro s fits TRAIL SWITCHBACK 800 2017–2018

The **MBRP 5892-M429625-42 Trail Performance Exhaust System** is a meticulously engineered aftermarket upgrade designed to elevate the performance, sound, and aesthetics of the **2017-2018 Polaris 800 Switchback Pro-S**, transforming it into a more dynamic and exhilarating off-road machine. Crafted from high-quality **409 stainless steel**, this exhaust system is built to withstand the rigors of demanding trails while delivering a striking visual presence with its **dual-tip design**, which not only enhances the bike s aggressive stance but also ensures optimal airflow and power output. The system features a **cat-back configuration**, meaning it replaces everything from the catalytic converter back, eliminating the need for modifications to the stock exhaust headers, and simplifying installation for both DIY enthusiasts and professional mechanics. Engineered with precision, the exhaust incorporates a **high-flow muffler** that maintains a balanced tone deep, resonant, and unmistakably sporty without sacrificing the clarity of the engine s voice, making it ideal for riders who crave both performance and a satisfying auditory experience. The **heat-shielded construction** ensures durability in extreme conditions, preventing warping or corrosion, while the **smooth, polished finish** adds a premium look that complements the Switchback Pro-S s rugged appeal. Whether tackling technical trails, carving through rough terrain, or simply cruising for fun, this exhaust system enhances throttle response, exhaust scavenging, and overall engine efficiency, allowing the 800cc V-twin to unleash its full potential. Backed by **MBRP s reputation for quality and reliability**, this exhaust is a standout choice for riders seeking a seamless blend of performance, style, and off-road capability.

### **Pros and Cons of the MBRP 5892-M429625-42 Trail Performance Exhaust for 2017-2018 Polaris 800 Switchback Pro-S**

1. **Improved Sound and Tone** The exhaust is designed to enhance the stock exhaust s sound, providing a deeper, more aggressive tone that appeals to riders who enjoy a louder, more aggressive exhaust note without being overly harsh.

2. **Better Flow and Horsepower** The Trail Performance exhaust is engineered to optimize exhaust flow, which can lead to slight improvements in horsepower and throttle response. This is particularly noticeable in mid-range power delivery, making the bike feel more responsive.

3. **Lightweight Construction** The exhaust is made from high-quality stainless steel, which is both durable and lighter than some aftermarket alternatives. This can contribute to a slight reduction in overall weight, improving handling and maneuverability.

4. **OEM Fitment with Upgrades** While it s not a direct OEM replacement, the MBRP exhaust is designed to fit the 2017-2018 Polaris 800 Switchback Pro-S with minimal modifications. It retains the stock mounting points, making installation relatively straightforward for those comfortable with basic mechanical work.

5. **Durability** MBRP (Motorcycle Brand Racing Products) is known for producing high-quality, long-lasting exhaust systems. The Trail Performance line is built to withstand the rigors of off-road use, including rocks, mud, and rough terrain.

6. **Aesthetic Appeal** The exhaust features a sleek, aggressive design that enhances the bike s appearance. The matte black finish with subtle detailing gives it a modern, sporty look that complements the Switchback Pro-S s aggressive styling.

7. **Compatibility with Other Upgrades** If you plan to add other performance parts (such as a high-flow air filter, upgraded intake, or ECU tune), this exhaust can pair well with those modifications to further enhance performance.

1. **Cost** The MBRP Trail Performance exhaust is more expensive than the stock exhaust. While it offers noticeable improvements, the price may be a deterrent for riders on a tight budget. Pricing can vary, but it typically ranges in the $800 $1,200 range depending on retailer and any additional accessories included.

2. **Installation Complexity** While the exhaust retains stock mounting points, installation still requires removing the stock exhaust, which involves disconnecting the muffler, heat shield, and exhaust pipes. This may require some mechanical skill or the assistance of a professional, adding to the overall cost if labor is involved.

3. **Potential Backpressure Issues** Some riders report that the exhaust can introduce slight backpressure if not paired with other performance upgrades (such as a tune or upgraded intake). This can sometimes result in a less smooth power delivery if the bike isn t otherwise optimized.

4. **Weight Distribution Shift** While the exhaust is lightweight, the placement of the new exhaust system may slightly alter the bike s weight distribution. This can affect handling, particularly in aggressive riding or when carrying heavy loads. Most riders find the difference negligible, but it s worth noting.

5. **Noise Regulations** Depending on your local laws, the louder exhaust note may violate noise ordinances. Always check local regulations before installing a louder exhaust, as some areas require mufflers that meet specific decibel limits.

6. **Limited Customization** Unlike some aftermarket exhausts that offer multiple tip sizes or tuning options, the MBRP Trail Performance exhaust is a fixed design. If you prefer a different sound profile or flow characteristics, you may need to explore other brands or models.

7. **Potential for Rust or Corrosion** While stainless steel is more resistant to rust than mild steel, it s not entirely immune. Off-road riders who frequently ride in wet or muddy conditions should ensure proper maintenance to prevent any long-term corrosion issues.

The MBRP 5892-M429625-42 Trail Performance exhaust is a high-quality upgrade for the 2017-2018 Polaris 800 Switchback Pro-S, offering noticeable improvements in sound, flow, and aesthetics. It strikes a balance between performance enhancements and practicality, making it a strong choice for riders who want a significant upgrade without drastic modifications. However, the cost and installation requirements may be prohibitive for some, and it s not a "set-and-forget" upgrade pairing it with other performance parts (like a tune or intake) will yield the best results.

If you prioritize a deeper, more aggressive sound, better throttle response, and a premium look while being willing to invest in a quality aftermarket part, this exhaust is an excellent choice. For riders on a budget or those who prefer minimal modifications, the stock exhaust or a more affordable aftermarket option might be more suitable.

- You want a noticeable improvement in sound and power delivery.

- You re willing to invest in a high-quality, durable exhaust system.

- You plan to pair it with other performance upgrades (e.g., a tune, air filter, or intake).

- You enjoy the aggressive tone and styling it provides.

- You re on a tight budget and prefer a more cost-effective upgrade.

- You re uncomfortable with installation or lack mechanical experience.

- Your local noise laws restrict louder exhausts.

- You prefer a more subtle performance boost without a significant change in sound.

For those who want a middle ground, alternatives like the **Polaris Performance Parts exhaust** (if available for your model) or **other mid-range aftermarket brands** (such as **Titanium Sports or Akrapovic**) may offer a balance between cost and performance. However, the MBRP exhaust remains one of the best options for riders who want a premium upgrade.
