High-performance slip-on mufflers featuring the HP-Plus patented, fiberglass-wrapped, steel construction sound control device. These mufflers provide significant gains in horsepower and torque and exhibit a distinctive, throaty sound. All models retain factory crossover features and mount to factory headers using all factory mounting hardware.

Okay, so maybe your budget isn´t ready for a new big ínch S&S engine yet. But better performance is still within your reach and you can have 10 extra rear wheel horsepower at a price that is about the best deal going. These kits consist of a set of S&S performance mufflers, a high flowing S&S teardrop air cleaner, and a jet kit to re-jet stock carburetors with all components installed in less than an hour. There is no engine work to do, and everything you need is included in the kits. They will fit on either a stock carburetor or a stock 2001-up Delphi style fuel injected throttle body. With the jet kit you can dial in the stock carb for maximum power gains and improved rideability when installed on carbureted bikes. Our testing has shown that fuel map adjustments are normally needed when installed on fuel injected models. It is recommended that the bike be calibrated by your local dealer to insure that the engine is receiving sufficient fuel.
