PERFORMANCE MOTORCYCLE PARTS AND KITS FOR AMERICAN V-TWINS

Step 1: S&S Intake and Exhaust

Everything to Gain Up to 10 hp! More Air - More Power!

That's what Step 1 of the S&S® 4-Step Performance Program is all about. A high flowing S&S intake makes more air available to your engine, and a set of S&S performance slip-on mufflers or complete exhaust system gets the exhaust out of the engine to make room for more air. Power is nothing without style, and S&S combines our legendary Proven Performance® with a lot of great looking options like air cleaners, tuned induction, and high performance exhaust.

Step 1 is the best deal going for easy, economical horsepower. Reasonable prices and easy installation keep the price tag under control, and in most cases you save more money because no tuning is required. However for the best performance and driveability, we recommend carburetor or EFI recalibration.

Keep your Harley-Davidson® motorcycle real deal with American made S&S intake and exhaust!

S&S Performance Exhaust

Power, Sound, and Style!
