Whether you re carving through deep mud, tackling rocky trails, or pushing the limits on the open road, this kit not only elevates the performance of your Polaris but also turns heads with its bold, custom aesthetic. Perfect for riders who demand both power and style, the Throttle MN/89KT Goldfinger Left Kit is a must-have upgrade for any serious off-road enthusiast looking to maximize their machine s potential.

The **Throttle MN/89kt Goldfinger Left Kit** is a popular aftermarket exhaust system designed for Polaris RZR 4, 5, and 6 models from the 2014 2021 generations. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the Throttle MN/89kt Goldfinger Left Kit**

1. **Performance Gains**

The kit is designed to improve exhaust flow, which can enhance throttle response and horsepower, particularly noticeable in mid-range RPMs. Many users report a more aggressive and linear power delivery, especially when paired with other performance modifications.

2. **Aesthetic Appeal**

The Goldfinger series features a sleek, aggressive design with a polished finish and a distinctive black-and-gold color scheme. It stands out as a premium-looking exhaust, appealing to those who prioritize style alongside performance.

3. **Sound Profile**

The kit produces a deep, growling exhaust note that is louder and more aggressive than the stock system. This is ideal for riders who enjoy a louder, more commanding sound without being overly harsh or obnoxious.

4. **Compatibility**

The kit is specifically designed for the 2014 2021 Polaris RZR lineup, ensuring a proper fit without major modifications required. It is compatible with both 4x4 and 4x4 Pro models, though some users may need to adjust mounting brackets for a perfect fit.

5. **Durability**

Throttle is known for manufacturing high-quality exhaust systems with sturdy construction. The Goldfinger kit uses heavy-duty materials, including stainless steel headers and a durable muffler, which should withstand regular use and off-road abuse.

6. **Ease of Installation**

While installation requires some mechanical skill, the kit comes with detailed instructions and is designed to be relatively straightforward compared to more complex exhaust systems. Many users complete the job in a few hours with basic tools.

7. **Positive Community Feedback**

The kit has garnered praise in off-road and ATV forums for its balance of performance, sound, and appearance. Many riders report noticeable improvements in both power and aesthetics without significant drawbacks.

---

### **Cons of the Throttle MN/89kt Goldfinger Left Kit**

1. **Cost**

The kit is priced higher than stock exhaust systems and some budget aftermarket alternatives. For a complete left-side exhaust (including headers, muffler, and piping), the cost can range from $800 to $1,200, depending on additional components like clamps or mounting hardware.

2. **Limited Right-Side Options**

The Goldfinger kit is designed as a left-side exhaust only. To complete the look, you would need to pair it with a right-side exhaust, which may require purchasing a separate kit (e.g., the Throttle MN/89kt Goldfinger Right Kit or another brand s right-side system). This adds to the overall cost and complexity.

3. **Potential Backpressure Issues**

While the kit improves exhaust flow, some users report that it may introduce slight backpressure if not paired with other performance modifications (e.g., a high-flow air filter or upgraded intake). This can sometimes lead to a slight loss of low-end torque or require tuning to optimize performance.

4. **Weight**

The kit is heavier than stock exhaust systems due to the use of durable materials. While this doesn t significantly impact handling, it may be a consideration for riders who prioritize lightweight modifications.

5. **Installation Challenges**

The kit requires removing the stock exhaust, which involves disconnecting the catalytic converter (if equipped) and possibly cutting or modifying existing piping. This can be tricky for beginners, and improper installation may lead to leaks or fitment issues.

6. **Sound Regulation Concerns**

While the sound is aggressive, some riders may find it too loud for legal use in certain areas where noise regulations are strict. The Goldfinger kit does not include a sound-deadening feature, so riders should check local laws before installation.

7. **Potential for Heat Buildup**

The kit s design may cause slightly higher exhaust temperatures due to improved flow and reduced restriction. This can lead to heat transfer to nearby components, though it is generally not a major issue unless paired with other high-performance modifications.

---

### **Conclusion**

The **Throttle MN/89kt Goldfinger Left Kit** is an excellent choice for Polaris RZR owners who want to enhance both the performance and appearance of their vehicle. It delivers a noticeable improvement in exhaust flow, a commanding sound profile, and a premium aesthetic. However, the higher cost, the need for a complementary right-side kit, and the potential for installation challenges are factors to consider.

If you are looking for a **left-side exhaust that stands out visually, improves power delivery, and fits seamlessly with your RZR**, this kit is a strong contender. That said, if budget or simplicity is a priority, you may want to explore alternative options like the **Throttle MN/89kt Right Kit** (for a complete system) or other brands with slightly lower price points.

---

### **Recommendation**

**Buy the Throttle MN/89kt Goldfinger Left Kit if:**

- You prioritize performance gains and a high-end aesthetic.

- You are willing to invest in a premium exhaust system and plan to pair it with a matching right-side kit.

- You have some mechanical experience or are willing to seek professional help for installation.

- You enjoy a loud, aggressive sound and are aware of local noise regulations.

**Consider alternatives if:**

- You want a complete exhaust system (left and right) without purchasing two separate kits.

- You are on a tighter budget and can find a similarly performing kit at a lower cost.

- You prefer a quieter or more subtle sound profile.

For the best results, pair this kit with other performance upgrades (e.g., a high-flow air filter, upgraded intake, or a tune) to fully realize its potential. Always ensure proper installation to avoid leaks or fitment issues.
