Red Thunder Exhaust and Arlen Ness Big Sucker Installed

A Harley-Davidson Dyna Low Rider learns to suck and blow

We have been hearing for a few years about an Italian-made exhaust known as Red Thunder. After many failed attempts we finally got our grubby hands on one to test on our 2015 H-D Dyna Low Rider. After hearing good things from the few folks in the US who had this pipe on their bikes, we knew we had to get an intake to match the upgraded performance exhaust. After a bit of thought we went with the tried-and-true Arlen Ness Bike Sucker due to the good luck we have had with them in the past as well as the unit’s classic good looks. Next month we will be putting the bike on the dyno and getting some real numbers, so stay tuned, but for now check out how we went about installing these simple yet effective bolt-on upgrades. HB
