Review GRAVES MOTOSPORTS Motorsports Yamaha 3/4 Titanium Exhaust fits R1 2015–2025

The **Graves Motorsports EXY-15R1-CETT-2 Yamaha R1 3/4 Titanium Exhaust System** is a meticulously engineered aftermarket performance upgrade designed to elevate the already formidable power delivery and exhaust note of the Yamaha R1 across its 2015 2025 model spectrum. Crafted from premium **3/4-inch titanium tubing**, this exhaust system is built to withstand the extreme thermal and mechanical stresses of high-revving super sport engines while delivering an aggressive, high-frequency exhaust tone that resonates with both the rider s ears and the road beneath. The **CETT-2** designation signifies a dual-tone design, featuring a **center exhaust tube with a tapered tip** for a sharper, more directional exhaust sound, paired with a **throat-tuned secondary tube** that enhances mid-range power and throttle response. The system incorporates **high-flow, precision-machined titanium mufflers** with optimized baffling to strike a balance between performance gains and a refined yet commanding exhaust note ideal for both track days and street riding. The **full titanium construction** ensures minimal weight penalty while maximizing durability, making it a preferred choice for riders seeking both aesthetic appeal and mechanical robustness. Compatible with the R1 s stock mounting points, the Graves EXY-15R1-CETT-2 integrates seamlessly with the bike s existing exhaust architecture, offering a direct bolt-on installation that preserves the R1 s factory alignment and handling dynamics. Whether chasing lap times on the track or cruising at high speeds on the highway, this exhaust system transforms the R1 into a more dynamic, responsive, and audibly striking machine, embodying the perfect fusion of performance and precision engineering.

### **Pros and Cons of buying a Graves Motorsports EXY-15R1-CETT Yamaha R1 3/4 Titanium Exhaust (2015 2025)**

#### **Pros**

1. **Performance Enhancement**

The EXY-15R1-CETT is a high-quality titanium exhaust designed to improve the Yamaha R1 s power delivery. Titanium is lighter than steel or stainless steel, reducing unsprung weight, which can improve acceleration and handling. The CETT (Catalytic Exhaust Tuning Technology) version is optimized for better mid-range torque and top-end power, making the bike feel more responsive.

2. **Lightweight Construction**

Titanium is significantly lighter than traditional exhaust materials, which helps reduce overall weight. This can lead to better throttle response, quicker acceleration, and improved agility, especially in high-speed maneuvers.

3. **Durability and Longevity**

Titanium is highly resistant to corrosion and heat, making it a durable choice for high-performance exhaust systems. Unlike steel or stainless steel, it does not rust easily, which is beneficial in varying weather conditions.

4. **Sound Quality**

The EXY-15R1-CETT is known for producing a deep, aggressive, and well-balanced exhaust note that enhances the R1 s already sporty sound. The tuning ensures a smooth powerband without excessive harshness.

5. **Compatibility with Stock and Modified R1s**

This exhaust is designed to fit the Yamaha R1 from 2015 to 2025, making it a versatile upgrade for both stock and modified bikes. It can be paired with other performance parts like ECU tunes, intake systems, or suspension upgrades for further gains.

6. **OEM-Like Fitment**

Graves Motorsports is a reputable brand known for high-quality aftermarket parts. The EXY-15R1-CETT is designed to fit seamlessly with the stock R1 exhaust system, requiring minimal modifications to install.

7. **Warranty and Support**

Graves offers warranties on their exhaust systems, providing peace of mind against manufacturing defects. Their customer support is generally reliable, with resources available for installation guidance.

---

#### **Cons**

1. **High Cost**

Titanium exhaust systems are significantly more expensive than steel or stainless steel alternatives. The EXY-15R1-CETT is a premium product, and the price reflects its quality and performance benefits. This may be a barrier for budget-conscious buyers.

2. **Installation Complexity**

While the exhaust is designed for easy fitment, installing it may require some mechanical skill, especially if additional modifications (like ECU tuning) are needed to optimize performance. Improper installation could lead to leaks or fitment issues.

3. **Potential Need for ECU Tuning**

The EXY-15R1-CETT can produce more power than the stock R1 s ECU is calibrated for. Without a tune, the bike may run rich, leading to poor fuel economy, reduced reliability, or even damage to the engine over time. A professional ECU tune (e.g., from YSS, RevTech, or a local tuner) is highly recommended but adds to the cost.

4. **Weight Savings May Be Marginal**

While titanium is lighter than steel, the weight difference compared to a high-quality stainless steel exhaust may be modest. The performance gains from reduced unsprung weight are real but may not be as dramatic as some riders expect.

5. **Limited Aftermarket Support**

If something goes wrong with the exhaust, finding replacement parts or technicians familiar with Graves titanium systems may be more challenging than with more common brands. This could lead to longer wait times for repairs.

6. **Potential for Resale Value Decline**

High-end aftermarket parts like titanium exhausts can depreciate faster than stock or more common upgrades. If you plan to sell the bike later, the added value of the exhaust may not fully offset its upfront cost.

7. **Noise Regulations**

While the EXY-15R1-CETT produces a sporty note, some riders may find it too loud for daily riding, especially in areas with strict noise laws. Always check local regulations before installing a high-flow exhaust.

---

### **Conclusion**

The Graves Motorsports EXY-15R1-CETT Yamaha R1 3/4 Titanium Exhaust is one of the best aftermarket upgrades available for the R1, offering significant performance benefits, durability, and a premium sound. Its lightweight titanium construction reduces unsprung weight, improves throttle response, and enhances the bike s overall feel. The CETT tuning ensures a balanced power delivery, making it ideal for both track and street use.

However, the high cost, potential need for ECU tuning, and installation considerations are drawbacks that must be weighed against the benefits. If you re serious about maximizing your R1 s performance and don t mind the investment, this exhaust is an excellent choice. For riders on a tighter budget or those who prioritize simplicity, a high-quality stainless steel exhaust (like a Dynacraft or Akrapovic) might offer a more cost-effective alternative with similar performance gains.

### **Recommendation**

**Buy the Graves EXY-15R1-CETT if:**

- You want the best possible performance and sound upgrade for your R1.

- You re willing to invest in ECU tuning to fully optimize the system.

- You prioritize durability and lightweight construction.

- You plan to use the bike for track days or aggressive riding where every bit of power and weight reduction matters.

**Consider alternatives if:**

- Budget is a concern (a stainless steel exhaust like the Dynacraft or Akrapovic may offer similar gains at a lower cost).

- You re not comfortable with ECU tuning or installation complexity.

- You prefer a more subtle sound or plan to ride in areas with strict noise laws.

Ultimately, the EXY-15R1-CETT is a top-tier upgrade that will make your R1 feel more aggressive and responsive, but it s best suited for riders who are committed to pushing their bike s limits.
