3 S&S Cycle Milwaukee-Eight Exhaust Upgrades

Power Rangers

Taking lessons learned from decades at the track and on the street, S&S Cycle has a long history of muscling up American V-twins, including the Milwaukee-Eight. In the ancient dinosaur times before Harley-Davidson fuel injected its engines, that meant S&S Cycles’ legendary carburetors. Now, the company offers bolt-on power via some cool exhaust pipes and systems, like these for the latest H-D Big Twin.

Combining a two into two format with a hidden crossover, the new Grand National system sports clean bends, stainless header tubing, and full shielding to create an exhaust that makes real power without the punishment of melted boots and uneven torque delivery of most other short tract systems. S&S also includes wide band O2 sensor ports as well as removable secondary baffles that allow for sound and backpressure tuning. Available in chrome or black ceramic.

Merging a full flow stainless header into a highly engineered collector and culminating in a 4.5-inch muffler, the new Sidewinder represents a combo plate of style and power. It includes their removable dB reducer baffle allowing riders to tune the system for sound and backpressure. Sidewinder is available for 2017-18 Harley-Davidson touring models. A CARB compliant version is coming soon.

S&S doesn’t build anything unless it makes power and the SuperStreet does exactly that with a claimed 86hp (+15%) and 110 lb./ft. Torque (+10%) out of the new generation of Milwaukee-Eight Softail models. Available with S&S designed high flow cat (49 state legal) or as a race-only version in ceramic black or chrome and made in the USA.
