If you want to go fast, but you don't want all the noise, the new S&S Stainless Performance Oval (SPO) touring style mufflers are just what you are looking for. With a pleasing low rumble, reminiscent of the big block muscle cars of the late 1960's, the new S&S SPO mufflers are easy on the ears while they add some extra muscle to your bike. In addition, the reasonable exhaust volume and the dual wall polished stainless steel construction allow you to listen to the blues on your stereo as you cruise down the highway, without worrying about your exhaust system turning blue while you do it. S&S SPO mufflers look great, but the most gratifying part is when the extra power takes you around that semi quickly and safely with just a twist of the throttle. If you need to make your bike even quieter, this accessory baffle can be installed in minutes, and reduces exhaust sound by an additional 3 dB. The original baffles can easily be replaced to restore the original sound and horsepower.
