Vance & Hines PCX Eliminator 300 Slip-On Mufflers For Harley Heritage & Deluxe (2018–2024)
Classic Bagger Heritage Styling Meets Advanced PCX Catalyst Performance
Elevate the acoustic presence, performance, and style of your Milwaukee-Eight Softail with the Vance & Hines PCX Eliminator 300 Slip-On Mufflers. Designed specifically for 2018 through 2024 Harley-Davidson Heritage Classic and Softail Deluxe models, these 3-inch diameter slip-on mufflers feature precision CNC-machined billet end caps and offer complete clearance for factory saddlebags and rear support brackets.
Powered by Vance & Hines’ proprietary PCX™ (Power Chamber Exhaust) technology, each muffler integrates a high-flow chambered catalyst that enhances low-to-mid-range torque response, reduces felt rider heat, and maintains 49-state federal emissions compliance.

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.
Vehicle Compatibility Guide
The Eliminator 300 slip-ons (Part #16321 Chrome / #46321 Black) are engineered specifically for the floorboard-equipped, dual-muffler Softail chassis and provide total clearance for OEM saddlebags:
Compatible Harley-Davidson Softail Models (2018–2024)
- Heritage Classic: FLHC (2018–2021)
- Heritage Classic 114: FLHCS (2018–2024)
- Softail Deluxe: FLDE (2018–2020)
Fitment Note: Engineered specifically for FLHC, FLHCS, and FLDE models. Will not fit mid-control or peg-control Softails (such as Street Bob, Low Rider S/ST, or Fat Boy) which require distinct mounting bracket configurations.
Step-by-Step DIY Installation Guide
Upgrading your Heritage Classic or Softail Deluxe with PCX Eliminator 300 slip-ons takes approximately 30 to 45 minutes using standard shop tools.
### Required Tools
- 3/8″ Drive Ratchet with 1/2″ and 9/16″ sockets
- Torque wrench (ft-lbs)
- High-temperature copper anti-seize lubricant
- Rubbing alcohol and a clean microfiber cloth
### Step 1: Removal of Factory Mufflers
Ensure the motorcycle is completely cool and safely resting on a kickstand or lift. Loosen the factory Torx exhaust clamps connecting the stock mufflers to the OEM collector head pipes. Remove the rear mounting bolts from the frame support bracket under each muffler. Twist and gently pull the stock mufflers rearward off the head pipes.
### 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.
