Installing Vance & Hines True Dual Exhaust

Vance and Hines true dual exhaust installed

Vance and Hines Performance Exhaust produces race-tuned performance exhausts for a variety of motorcycle makes and models. Vance and Hines exhaust systems are known for their characteristic sound and increased horsepower, especially on Harley Davidson Motorcycles. Many of today’s motorcycles are equipped with V-twin engines or similar setups, having multiple exhaust ports choked down into a single exhaust outlet. Vance and Hines produces a true dual-exhaust system that opens up your bike’s airways and adds horsepower. The true dual exhaust has a single exhaust pipe for each exhaust port and produces a deep, rich tone while increasing throttle response and overall horsepower.


1. Spray WD-40 on the header bolts located on the exhaust port of each cylinder of your motorcycle engine. The lubricant will work into the threads of the bolts and allow easier removal. Using the ratchet set, remove the header bolts from each exhaust port (there should be two per port).

2. Examine the remainder of the exhaust piping and locate any bolts or screws holding the exhaust to the motorcycle frame. Remove the bolts and carefully store them somewhere where they won’t get lost. You may need to remove a few body panels to disconnect the entire system, but this can be accomplished by using a screwdriver to remove the screws holding the body panels on.

3. Remove the old header gaskets from the exhaust ports and replace with the new set from your gasket kit. Fit one exhaust pipe on your rear cylinder and reinstall the header bolts.

4. Tighten the bolts down to the manufacturer’s specifications and reinstall the bolts that mount the exhaust pipe to the frame.

5. Repeat this process for the second exhaust pipe. Reinstall any body panels that were removed and start the bike for a test drive.
