Performance Engineering & Acoustic Output
### High-Velocity PCX™ Catalyst Technology
Standard catalyst placement in factory touring headers builds excess heat near the rider’s legs and restricts exhaust gas pulse velocity. Vance & Hines’ proprietary PCX™ technology integrates a chambered high-flow catalyst directly into the Big Radius muffler bodies. This increases exhaust pulse velocity, optimizes backpressure, and yields a dramatic boost in mid-range pass-through power for heavy touring motorcycles.

Step-by-Step DIY Installation Guide
Installing a complete Vance & Hines PCX Big Radius 2-Into-2 system takes approximately 60 to 90 minutes using standard shop tools.
### Required Tools
- 3/8″ Drive Ratchet with 1/2″, 9/16″, and 7/16″ sockets
- Torx key set (T27 / T30)
- O2 sensor socket or 22mm combination wrench
- New exhaust port gaskets (screamin’ eagle flat style recommended)
- Clean microfiber towel & rubbing alcohol (for post-install cleaning)
### Step 1: Removal of Stock Touring Exhaust
Disconnect oxygen (O2) sensor leads. Unbolt and remove the factory saddlebags, heat shields, cross-over pipe, stock mufflers, and header flanges from the cylinder heads. Carefully extract the factory O2 sensors from the original headers.
### Step 2: Gasket Replacement & Flange Assembly
Remove old exhaust port gaskets from the engine cylinder heads and replace them with fresh high-performance gaskets. Transfer the stock exhaust flanges and retaining rings onto the primary header tubes of your new Vance & Hines Big Radius system.
### Step 3: Mounting & Torque Sequence
Install the provided O2 sensor adapters and thread in the factory sensors. Loosely mount the main exhaust support bracket to the transmission housing. Position the front and rear head pipes into the cylinder ports and thread the flange nuts finger-tight. Align the system, attach all mounting hardware, torque exhaust port nuts to factory torque specs (100–120 in-lbs), and clean all hand oil off the heat shields before starting the engine.
Frequently Asked Questions
### Is an ECU tuner required when installing this full exhaust system?
Yes. Because the PCX Big Radius replaces the entire factory head pipe and muffler assembly, an ECU re-tune using an aftermarket tuner (such as the Vance & Hines Fuelpak FP4) is strongly recommended to optimize air-fuel ratios and prevent lean running conditions.
### Is this system 50-state emissions legal?
Yes. The integrated PCX™ high-flow catalyst core meets EPA and CARB emissions standards, making this full exhaust system fully compliant for street use across all 50 US states.
