Vance & Hines Supersport 2-Into-1 Performance Exhaust System For Harley Softail (2018–2026)
Race-Derived Stepped Headers & Lightweight High-Clearance Bagger/Club-Style Performance
Transform the acceleration, cornering clearance, and acoustic note of your Milwaukee-Eight Softail with the Vance & Hines Supersport 2-Into-1 Exhaust System. Engineered specifically for 2018 through 2026 Harley-Davidson Softail models, the Supersport series blends track-tested 2-into-1 stepped header dynamics with a compact, high-upswept muffler design.
Precision hand-TIG welded from high-grade stainless steel, the Supersport system merges equal-length primary headpipes into a tuned collector. This design accelerates exhaust gas scavenging, eliminating mid-range torque dips and delivering aggressive roll-on power. Its high-and-tight stance gives hard-riding street and canyon riders maximum lean angle without scraping exhaust components.

Performance Engineering & Acoustic Dynamics
### Advanced Stepped Header Scavenging
Unlike standard dual pipes that suffer from reverted backpressure waves, the Vance & Hines Supersport utilizes progressive stepped primary headers. By expanding primary tube diameters step-by-step into the 2-into-1 merge collector, exhaust gases maintain high velocity. This vacuum effect pulls burnt fuel mixture out of the combustion chamber, allowing your M8 engine to draw in a denser intake charge for crisp throttle response.
### Aggressive Tone & High-Clearance Lean Angle
Designed with club-style and performance bagger aesthetics in mind, the Supersport muffler tucks tightly against the Softail frame. The upswept angle keeps the system clear of the asphalt during deep cornering, while the high-flow internal core produces an unmistakable, deep V-Twin growl under hard acceleration.

Step-by-Step DIY Installation Overview
Installing a Vance & Hines 2-into-1 exhaust system is a straightforward mechanical procedure. Estimated installation time: 2 to 3 hours.
### Required Tools
- Motorcycle Frame Jack / Center Lift
- 3/8″ Drive Torque Wrench & Socket Set
- 1/2″ & 9/16″ Combination Wrenches
- O2 Sensor Wrench and fresh exhaust port gaskets
### Step 1: Stock Exhaust System Removal
Secure the bike on a center frame lift. Unplug the front and rear oxygen sensor harnesses. Unbolt support brackets, flange nuts at the cylinder heads, and remove the stock exhaust system along with old cylinder gaskets.
### Step 2: Bracket Mounting & Exhaust Port Prep
Thoroughly clean the cylinder exhaust ports and seat fresh high-performance wire-woven gaskets. Mount the new Vance & Hines frame bracket loosely to the Softail frame to allow alignment leeway during header fitting.
### Step 3: Installing Headers, Muffler & Reconnection
Transfer O2 sensors into the bungs using anti-seize compound on the threads. Fit primary headers onto the head studs, align the collector, slide on the upswept muffler, and torque flange nuts to factory specs. Clean the pipes with solvent to remove fingerprints, reconnect O2 sensors, and start the engine to verify proper seals.
Frequently Asked Questions
### Do I need to re-tune my Milwaukee-Eight Softail after installing the Supersport 2-1 exhaust?
Yes. Installing a high-flow 2-into-1 performance exhaust alters air-fuel ratios significantly. Re-mapping your ECU with an aftermarket tuner like the Vance & Hines Fuelpak FP4 or Dynojet Power Vision ensures peak horsepower gains and keeps the engine running at safe operating temperatures.
### Does this exhaust fit with saddlebags installed on Low Rider ST models?
Yes. The Vance & Hines Supersport system is designed specifically with bag clearance in mind, sweeping up cleanly beneath stock OEM factory saddlebags on Low Rider ST (FXLRST) and Sport Glide models without heat interference.
