Cobra Engineering released these Swept Speedsters ($689.95) for Softail models. We had an ’08 Rocker C model that was looking for an upgrade. Essentially, this is a 2-into-1 system that looks like a 2-into-2 but it’s been outfitted with a Power Port that connects the mufflers to increase horsepower and torque numbers. We also installed Cobra’s Fi2000R O2 ($279.95) fuel management system, and a K&N; Engineering RK Series high-flow air cleaner kit ($215.95).
