Union 2 into 1 Exhaust System
Union 2 into 1 Exhaust System: Unleash Your Motorcycle's True Potential
The Union 2 into 1 Exhaust System is the perfect choice for riders looking to enhance their motorcycle's performance and sound. With its innovative design, this system optimizes torque and horsepower while giving your bike a deep, rich exhaust note that commands attention on the road.
Transform Your Ride with Performance Engineering
This exhaust system features a unique 3-step header pipe design that transitions from 1 3/4" to 1 7/8" to 2". This engineering not only improves exhaust flow but also helps prevent reversion, ensuring that your bike performs at its best. Riders can expect to feel a significant boost in acceleration and overall performance.
Customizable Sound with Removable Baffles
The Union exhaust comes equipped with an exclusive 2-step removable baffle that adjusts from 2 1/2" to 3". This feature allows you to customize the sound of your motorcycle to fit your riding style. For those who prefer a quieter ride, an optional quiet baffle is also available, making it easy to switch between a loud, aggressive sound and a more subdued tone.
Durable and Stylish Design
Made with a heavy-duty 16 gauge material, the 2 1/2" 220º heat shields provide excellent protection against heat while maintaining a sleek look. The 4" diameter slash-cut end cap features a rolled edge that can be mounted either up or down, allowing you to personalize your bike's appearance while enhancing its functionality.
