Vance & Hines 2-into-1 Upsweep Full Exhaust For Harley Sportster (2004–2013)
High-Performance Upswept Megaphone Engineering for Rubber-Mounted Sportsters
Give your modern-classic Sportster a aggressive, race-inspired transformation with the Vance & Hines 2-into-1 Upsweep Full Exhaust System. Precision-engineered specifically for 2004 through 2013 Harley-Davidson Sportster (XL) models, this performance exhaust combines high-velocity equal-length header pipes into a single upswept mega-muffler for maximum lean angle and aggressive cornering clearance.
Constructed with full-coverage heat shields to eliminate thermal discoloration, the 2-into-1 Upsweep features a stepped header design that increases exhaust gas scavenging. The result is a noticeable surge in mid-range torque, improved throttle response, and a crisp, throaty V-Twin bark under hard acceleration.

Performance Engineering & Acoustic Output
### Stepped Header & Collector Dynamics
Unlike standard dual pipes that allow exhaust pulse reversion, the Vance & Hines 2-into-1 Upsweep uses tuned stepped primaries that feed into a collector junction. This accelerates exhaust gas velocity, pulling spent gases out of the combustion chamber more efficiently and allowing your Evolution 883 or 1200 engine to breathe deeper.

Step-by-Step DIY Installation Guide
Installing a Vance & Hines 2-into-1 Upsweep full 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 18mm/22mm wrench (for 2007–2013 EFI models)
- New high-performance exhaust port gaskets
- Clean microfiber towel and degreaser
### Step 1: Removal of Factory Sportster Exhaust
Ensure the bike is cool and supported securely. Disconnect O2 sensor plugs (if equipped on 2007+ models). Unbolt the stock muffler support brackets from the frame and remove exhaust flange nuts from the cylinder heads. Carefully detach the original header pipes and mufflers as a complete assembly.
### Step 2: Gasket & Flange Preparation
Remove old crushed wire exhaust port gaskets from cylinder heads and replace with new flat screamin’ eagle style gaskets. Transfer existing flange rings and retaining clips onto the new primary tubes of your Vance & Hines headers.
### Step 3: Mounting & Torque Sequence
Thread O2 sensors (or provided plugs for 2004–2006 carbureted models) into the collector bungs. Loosely mount the main exhaust support bracket to the transmission frame mount. Insert headers into cylinder ports, thread flange nuts finger-tight, slide on the upswept megaphone collector, and torque header flange nuts evenly to 100–120 in-lbs.
Frequently Asked Questions
### Is an ECU tuner or jet kit required after installing this exhaust system?
Yes. Installing a full 2-into-1 performance exhaust significantly increases airflow velocity. For 2007–2013 EFI models, an ECU re-tune using a tuner (such as the Vance & Hines Fuelpak FP4) is strongly recommended. For 2004–2006 carbureted models, re-jetting the carburetor is required to ensure smooth running and avoid a lean condition.
### Will this exhaust work with passenger footpegs?
Due to the aggressive high-upswept angle of the rear collector, passenger peg mounts may require relocation kits or removal depending on your specific Sportster subframe trim.
