When consulting with motorcycle mechanics about their favorite exhaust for the Street Twin, one requirement consistently topped their list—great sound without sacrificing performance. Having personally tested several options, I can tell you that the Vance and Hines 16672 Twin Slash Round 4in. Chrome Slip-On stood out. It offers that aggressive rumble, thanks to its signature Twin Slash End Treatment, while maintaining a smooth throttle response. It’s durable, easy to install, and transforms your bike’s aesthetic instantly.
Compared to other options like the Rinehart Racing DBX45 or MagnaFlow’s Street Series, the Vance & Hines slip-on balances sound quality, build, and affordability. The Rinehart offers superior materials and a sleek black finish, but at a higher price and heavier weight. MagnaFlow provides a resonant, rich sound but slightly reduces low-end torque. The Vance & Hines maintains a perfect sweet spot—robust performance, a signature look, and solid value. After thorough testing, I confidently recommend it as the best exhaust for the Street Twin.
Top Recommendation: Vance and Hines 16672 Twin Slash Round 4in. Chrome Slip-On
Why We Recommend It: This slip-on offers a bold, deep sound without excessive drone. The Twin Slash design enhances performance by improving exhaust flow, boosting torque, and adding style. Its chrome finish is durable and eye-catching, and its ease of installation makes it a top choice. Compared to the Rinehart’s heavier, pricier black model or MagnaFlow’s louder tone, the Vance & Hines excels in delivering balanced, high-quality sound and performance at a favorable price point.
