Acoustic Engineering & Power Performance
### Louvered Core Baffle Design for Trike Power
Milwaukee-Eight trikes carry significantly more weight than two-wheeled touring models, placing heavier demands on the engine during acceleration. Factory exhaust mufflers trap heat and restrict airflow. Vance & Hines designed the Twin Slash system with an optimized louvered core baffle that balances backpressure, protects low-end pulling torque, and delivers a deep bass rumble without harsh highway drone.
### Key Performance Benefits

Step-by-Step DIY Installation Guide
Upgrading your Harley trike exhaust with Vance & Hines Twin Slash Slip-Ons takes under 45 minutes using standard shop tools.
### Required Tools
- 3/8″ Drive Ratchet with 1/2″ and 9/16″ sockets
- Torx key set (T27 / T30)
- Exhaust clamp removal tool or combination wrenches
- Penetrating lubricant
- Clean microfiber towel
### Step 1: Removal of Factory Trike Mufflers
Ensure the trike is completely cool and safely supported on a level surface. Spray penetrating oil onto the inlet joint connections. Unbolt the rear mounting screws located near the rear body work holding the stock mufflers to the frame brackets. Loosen the factory Torca clamps on the header pipe, then gently twist and slide the stock mufflers rearward until free.
### Step 2: Prepping Clamps & Slide Alignment
Slide new heavy-duty exhaust clamps over the expansion inlets of your new Vance & Hines Twin Slash mufflers. Apply a thin layer of anti-seize or lubricant to the header pipe tips to facilitate smooth positioning.
### Step 3: Mounting the Twin Slash Mufflers
Slide the Vance & Hines mufflers forward onto the header pipe outlets until fully seated against the stops. Align the rear bracket mounting points with the trike frame mounts. Hand-tighten the mounting bolts, verify that both twin slash tips align evenly with the body cutouts, and torque all hardware and clamps to factory service specifications.
Frequently Asked Questions
### Is an ECU re-tune required when installing Twin Slash slip-ons on a trike?
No. If you are installing these slip-on mufflers while keeping the stock air cleaner and factory header pipes, an ECU re-tune is not mandatory. However, pairing them with a high-flow air intake and an ECU tuner (like the Vance & Hines Fuelpak FP4) will maximize horsepower and torque gains.
### Do these mufflers clear the rear bodywork and bumper of the Freewheeler and Road Glide 3?
Yes. Vance & Hines specifically sizes and shapes the inlet length and body profile of these trike slip-ons to match the exact rear body cutouts of the FLRT Freewheeler and FLTRT Road Glide 3 chassis.
