Video-In this completely free tutorial video, we show you exactly how to install Python True Dual head pipes on a Harley Davidson touring motorcycle. This header system gets rid of your catalytic converter (cat), opening up the flow, increasing power & sound, & greatly reducing heat on the rider. Cats create a large amount of heat.
Note: Always check your local, state, and federal laws regarding motorcycle exhaust systems.
The Python true duals are just that, two separate pipes all the way from the heads to the rear. There is no chamber, so the back pressure is just not there. It's well known that true duals are not the number one choice for optimal performance anyway. They look great and sound good though. And most riders would not feel a noticeable loss of performance. These pipes only come with 12mm O2 ports, which is great because you can use your stock Harley O2 sensors. You'd have to have 18mm ports welded in if you wanted to use aftermarket wide-band O2 sensors.
We didn't notice any significant increase or decrease in performance after install of these Python True Duals. However, we did notice a great improvement in sound and the reduction of heat from having no cats. We do have some back pressure with these Pythons because Big Daddy is running Vance & Hines Eliminator 400 slip-on mufflers with them.
Remapping your motorcycle's Electronic Fuel Injection (EFI) is necessary when you change the flow of exhaust or air intake on your Harley, such as we did in these exhaust installs. Make it easy and get a V&H Fuelpak 3 Electronic Fuel Injection Tuner from our store. We highly recommend this EFI tuner and we use it heavily here at Law Abiding Biker™ Media.
