Review VANCE HINES Inch And Slash Rounds Slip On Mufflers Exhaust fits TWIN M8 TOURING 1926–2017

The **Vance Hines 48520 17-26 M8 Touring Twin Slash Rounds Slip Mufflers** are a meticulously engineered exhaust system designed to elevate the performance, aesthetics, and sound of modern muscle cars, particularly those built on the M8 platform such as the iconic 2014-2019 Ford Mustang GT and the 2015-2020 Ford F-150 Raptor. Crafted from high-quality **304 stainless steel**, these slip mufflers are built to withstand the rigors of high-performance driving while delivering a striking visual upgrade and a deep, resonant exhaust tone that turns heads on the road or track. The **17-inch diameter** of the mufflers ensures a substantial increase in exhaust flow compared to stock systems, reducing backpressure and allowing the engine to breathe more freely, which translates to improved throttle response and horsepower gains especially noticeable in high-revving applications. The **M8 Touring** designation speaks to their compatibility with the Mustang s signature **M8 exhaust system**, ensuring a seamless fit with the factory headers, downpipes, and catalytic converters, though they are also widely used in aftermarket builds where stock exhaust components are swapped out. The **Twin Slash Rounds** design is both functional and stylish, featuring a bold, aggressive shape with dual slashes on each side that not only enhance the car s aggressive stance but also contribute to the exhaust s signature tone a growling, mid-range rumble that s rich in harmonics, offering a more engaging and dynamic sound profile than traditional straight-pipe setups. These mufflers are also **fully welded and polished**, ensuring a durable, corrosion-resistant finish that maintains its showroom shine for years. Whether paired with a mild tune or a full-blown supercharged or turbocharged build, the Vance Hines 48520 delivers a perfect balance of performance, aesthetics, and sound, making it a standout choice for enthusiasts who demand both power and presence in their vehicles.

### **Pros and Cons of Buying Vance Hines 48520 17-26" M8 Touring Twin Slash Rounds Slip Mufflers Exhaust**

1. **Sound Quality** These mufflers are designed to produce a deep, aggressive tone with a balanced exhaust note, offering a more engaging sound than stock or overly restrictive aftermarket options. The "Slash Rounds" design helps maintain a smooth yet muscular exhaust growl.

2. **Performance Benefits** While primarily an aesthetic and sound upgrade, the slip-on design and slightly larger diameter (compared to stock) can help reduce backpressure, potentially improving throttle response and engine efficiency in some cases.

3. **Durability** Vance Hines exhaust systems are known for their high-quality construction, using heavy-gauge steel and corrosion-resistant coatings. This makes them suitable for daily driving and off-road use.

4. **Aesthetic Appeal** The aggressive, rounded design with a dual-tone finish (black with silver accents) gives a modern, custom look that stands out compared to stock exhausts. The slip-on style also allows for a cleaner, more integrated appearance.

5. **Compatibility** These mufflers are designed specifically for the 17-26" M8 Touring model, ensuring a proper fit without the need for extensive modifications. They are also part of a complete exhaust system, which can simplify installation.

6. **Sound Customization** The "Touring" designation suggests a balanced sound that isn t overly loud (though still noticeable), making it a good middle ground for those who want a sporty exhaust note without violating noise regulations in many areas.

7. **Warranty and Support** Vance Hines offers warranties on their products, and they have a reputation for good customer service, which can be reassuring for buyers.

---

1. **Cost** High-quality exhaust systems like this one are not cheap. The price point may be prohibitive for budget-conscious buyers, especially when factoring in installation labor if not doing it themselves.

2. **Noise Concerns** While the "Touring" designation implies a more civilized sound, the exhaust still produces a noticeable growl that may not be suitable for all environments (e.g., residential areas, workplaces, or areas with strict noise ordinances). Some users may find it too loud for daily driving.

3. **Installation Complexity** Replacing the entire exhaust system (or even just the mufflers) requires removing the old exhaust, which can be labor-intensive, especially for those without mechanical experience. Professional installation will add to the cost.

4. **Weight** Heavy exhaust systems can slightly reduce fuel efficiency due to added weight, though the impact is typically minor compared to other modifications.

5. **Potential Backpressure** While the slip-on design helps reduce backpressure, some aftermarket exhausts can still restrict flow if not properly matched to the engine. This system is designed to work well with the M8, but improper installation (e.g., leaks, misalignment) could negate performance gains.

6. **Resale Value Impact** While the exhaust improves the car s appearance and sound, it may not significantly boost resale value, especially if the car is sold to someone who prefers stock or quieter exhausts.

7. **Maintenance Considerations** Exhaust systems can develop leaks over time, particularly at welds or slip-on joints. Regular inspections are recommended to ensure longevity.
