One of the most popular and cost effective performance upgrades you can make to a Harley-Davidson® motorcycle is to replace the stock exhaust with a set of low restriction, high performance mufflers. The stock exhaust head pipes and S&S performance mufflers make a great high performance exhaust system with a low price tag.
It may be necessary to re-jet the carburetor or recalibrate the fuel injection system for best performance when a change is made in the exhaust system.
