PCX Technology & Engine Performance

### High-Flow Catalyst & Mid-Range Acceleration

Standard aftermarket drag pipes or open mufflers often suffer from a loss of backpressure, resulting in a sluggish low-RPM throttle response. The PCX (Power Chamber Exhaust) cartridge uses a double-matrix chambered high-flow catalyst. This creates effective exhaust pulse scavenging to boost torque right in the primary 2,000 to 4,000 RPM cruising range.

### Rider Comfort & Thermal Management

By positioning the high-flow catalyst downstream inside the muffler body, PCX technology helps reduce radiated exhaust heat—lowering overall operating temperatures at the rider footboards and passenger pegs compared to unshielded stock exhaust systems.

### Step 2: Preparing the PCX Eliminator 300s

Apply a thin coating of high-temperature anti-seize onto the expansion joints of the factory collector pipes. Slide the new heavy-duty Torca barrel clamps onto the front inlets of your Vance & Hines Eliminator 300 slip-ons.

### Step 3: Mounting and Alignment

Slide the Eliminator 300 mufflers onto the head pipes until they seat against the stopper stops. Align the integrated mounting channels with your frame’s rear bracket points. Thread in the mounting bolts finger-tight. Check from the rear to confirm both 3-inch muffler bodies sit level and clear saddlebag mounts.

### Step 4: Torque Specs & Degreasing Wipe-Down

Torque the rear mounting bracket bolts to 18 ft-lbs and the front barrel clamps to 38–42 ft-lbs.
CRITICAL WARNING: Clean all chrome or black surfaces thoroughly with rubbing alcohol prior to starting the engine. Fingerprints or oil residues left on the exhaust will permanently bake into the finish when heated!

Frequently Asked Questions

### Is fuel re-tuning required for these slip-ons?

Because PCX technology maintains proper backpressure and airflow balance, fuel tuning is optional if installed on an otherwise stock bike. However, adding a tuner like the Vance & Hines Fuelpak FP4 will optimize throttle response and air-fuel ratios for maximum performance.

### Can I install quiet baffles in the PCX Eliminator 300?

No. Due to the internal chambered catalyst core of the PCX cartridge, these slip-ons are not compatible with standard optional quiet baffle inserts.

PCX Technology & Engine Performance

High-Flow Catalyst & Mid-Range Acceleration

Standard open exhausts can cause a loss of backpressure, resulting in a sluggish low-RPM throttle response. The PCX (Power Chamber Exhaust) cartridge uses a double-matrix chambered high-flow catalyst. This creates effective exhaust pulse scavenging to boost torque right in the primary 2,000 to 4,000 RPM cruising range.

Rider Comfort & Thermal Reduction

By positioning the high-flow catalyst downstream, PCX technology helps reduce radiated exhaust heat—lowering temperatures at the foot pegs and passenger area compared to unshielded stock exhaust systems.

Engineered specifically as a drop-in insert for Vance & Hines 4″ Eliminator series mufflers, this quiet baffle reduces overall exhaust output by 2 to 3 decibels (dB). Whether you want to maintain neighborhood peace during early morning warm-ups or eliminate high-speed helmet drone on long touring rides, this baffle offers a smoother, deeper, and more refined exhaust frequency.

Made in the USA from heavy-gauge steel and wrapped in high-density thermal fiberglass packing, the Eliminator 400 Quiet Baffle tones down harsh high-pitched exhaust barks while preserving essential engine backpressure for broad low-end torque response.

Technical Specifications & Product Details

The **Vance & Hines Quiet Baffle** (Part #21859) for the **Eliminator 400 (4″) Slip-On Mufflers** is designed to tone down the exhaust volume while deepening the overall exhaust note.### Key Details & Specs* **Part Number:** Vance & Hines **21859**
* **Decibel Reduction:** Lowers sound output by approximately **2 dB to 4 dB** compared to the standard baffle.
* **Tone:** Reduces harsh high-frequency harshness, producing a deeper, rumbling exhaust note rather than an aggressively loud bark.
* **Fitment:** Engineered specifically for Vance & Hines **Eliminator 400 (4-inch)** Touring Slip-On Mufflers (commonly installed on Harley-Davidson Touring models).
* **Performance:** Provides slightly more backpressure, which can help smooth out low-end torque on some fuel-injected setups.—### What to Expect vs. Standard Baffles| Feature | Standard Eliminator Baffle | Quiet Baffle (#21859) |
| :— | :— | :— |
| **Volume Level** | Loud, aggressive roar | Moderately loud, deep rumble |
| **Harshness/Bark** | High under heavy acceleration | Mellowed out, smoother |
| **Highway Drone** | Noticeable at steady speeds | Significantly reduced for long rides |
| **Backpressure** | Lower | Slightly higher |—### Installation Tips1. **Tools Needed:** Allen wrenches, a small slide hammer or hook tool, and thread locker (e.g., Loctite 243).
2. **Removing Old Baffles:** Standard baffles can stick due to heat cycling and carbon buildup. Spray a light lubricant (like WD-40) inside the end cap perimeter and let it sit before pulling.
3. **Inserting New Baffles:** Ensure the fiberglass wrapping stays tightly wound around the baffle body during insertion. Wrapping painter’s tape around the fiberglass can help compress it; the tape will burn off harmlessly once the exhaust gets hot.
4. **Secure Fasteners:** Always apply medium-strength thread locker to the retaining screws to prevent them from vibrating loose.

Slide the Quiet Baffle into the Pro Pipe muffler body until the threaded mounting nut aligns with the hole in the exhaust shell. Thread in the retaining bolt securely and tighten down.

Frequently Asked Questions

Do I need to re-tune my fuel map after installing the Quiet Baffle?

If you are switching from the standard Pro Pipe baffle to the Quiet Baffle on a stock or Stage 1 motorcycle, fuel tuning is usually optional because total airflow changes are minimal. However, re-flashing your ECU with a tuner like the Vance & Hines Fuelpak FP4 ensures optimal air-fuel ratios and peak engine efficiency.

Does this quiet baffle fit other Vance & Hines exhaust models?

No. This quiet baffle is engineered specifically for Vance & Hines Pro Pipe 2-into-1 systems. Other exhaust families (like Twin Slash, Shortshots, or Hi-Output) require their own dedicated quiet baffle part numbers.
