The new Screamin' Eagle Thunder Street Performance Slip-On Mufflers - Jet Black (P/N 65430-10, $399.95) from Harley-Davidson Genuine Motor Accessories deliver an increase in torque and horsepower the rider can feel.

For the first time, these mufflers can be fitted with dramatic Black with Chrome Spears End Caps (P/N 65100013, $149.95).

Developed to work with header-mounted catalysts, these 3.5-inch mufflers feature an open-baffle design that produces a rich, deep bass note that meets 50-state sound level requirements. The rich, black-ceramic coating offers unmatched durability and look perfect with Dark Custom styling elements.

These easy-to-install slip-on mufflers make a pronounced styling and sound statement.

These mufflers fit 2009 California Touring models and 2010-later 50-state Touring models (except Trike and 110 cubic inch models).

The 2010 Street Glide and Tour Glide Custom models require the separate purchase of the Touring 2-into-2 Head Pipe Kit.

Installation also requires the separate purchase of an end cap kit and muffler clamps. See an authorized Harley-Davidson dealer for fitment details.
