Harley Exhaust Systems

Make a big statement with a full aftermarket Harley exhaust system. A full exhaust system is the best way to completely alter the style, sound, and performance of your Harley. Finding exactly what you’re looking for is easy with our giant selection at Dennis Kirk. We carry full systems from all the top exhaust brands like Thunder Header, Vance & Hines, Bassani, Freedom Performance, Cobra and more. All the different options truly allow you to choose what is best for you.

By swapping both the headers and the slip-ons, the amount of airflow can be dramatically impacted. Choosing a more free-flowing system can greatly improve performance. When doing this upgrade, it is also important to address the fuel tune and air cleaner. The engine needs more air/fuel to be allowed into it to make use of the performance exhaust system. When all done in conjunction, you will really notice a difference over your stock setup.

Style and sound are other considerations to make when choosing Harley exhaust systems. The header design and shape and color of the slip-ons all make a difference. With your V-Twin, you can also choose between a 2-into-1 or 2-into-2 system. Each will deliver their own style and performance. Chrome or powder coated black are other choices you have. Some systems have a combination of both.
