Aftermarket exhaust will bring better performance, more power, and better sound to your Harley Davidson. Stock Harley Davidson and other motorcycle pipes have catalytic converters in them, because of federal manufacturing emission laws. These “cats” as we call them really don’t let things flow and rob you of power and performance.
Many aftermarket performance head pipes come free and clear of cats and that will make a huge difference in performance and sound. Additionally, the cats cause a lot of extra heat where gases are caught up and restricted, thus putting the heat onto the rider. Your pipes in the area of the cats can get red hot, but they are usually covered by heat shields, so you don’t really see this.
The stock mufflers also have very restrictive baffles in them that also hinder flow. Many after market pipes have smaller baffles, but remember that smaller baffles means a louder motorcycle.
After you make alterations to a motorcycle’s exhaust system or air intake system by opening it up, you will need to re-map your electronic fuel injection (EFI) for the motor to run properly. You can really tune your EFI with aftermarket tuners. This is a great way to gain power and performance and you will definitely notice. We have tutorial videos and everything you need to know about EFI tuners and tuning your motorcycle.
