Product Description


Cobra Slip-On Slashdown Mufflers

The classic slash down look. The design cuts back under the bag, directing sound waves downward.

These award winning slip-ons for Harley Baggers are beloved by editors and real-world riders alike. That's because Cobra Slip-ons provide increased horsepower and torque with a deeper, more aggressive exhaust note. The 4" muffler body has proprietary technology to prevent bluing. With the louvers located further back in the muffler, super-heated gasses get a chance to cool before exiting the silencer core making Cobra Dresser mufflers virtually blue proof.

Questions & Answers

  • Are they load enough for the rider that likes to be heard?

    By: BuckSgt

    All of Cobra's mufflers are certainly louder than the stock exhaust system. Whether or not they're loud enough for your taste, well - that's a rather subjective matter. If you were to find that they're still not loud enough for your needs, then you could add a set of Cobra True Dual headers to go along with the mufflers at some point in the future. With that combination, you'd be assured loud pipes, by anyone's standards!

  • Can the some baffles be removed by the rider to make them louder like some others?

    By: Buck

    Yes, Cobra's Slashdown slip-on mufflers are equipped with removable baffles. A single screw secures each one in place, so removing them is a simple affair. Of course, once you pull the baffles, the mufflers will be quite a bit loader.

  • Will I need to remap with these?

    By: Booger

    For most modern bikes, it's not really required. Though, you may find the bike doesn't have the same throttle response after you install the mufflers, especially if it's carbureted. The only way to find out, of course, is to install the exhaust and see how the bike runs. In the case that it runs to your satisfaction, there's usually nothing to worry about. However, if you want to get the biggest possible power gain and the best throttle response out of the new exhaust, we (and Cobra) recommend a Cobra Jet Kit or a Cobra Fi2000R fuel controller if your bike is fuel-injected. Both of those components come with easy-to-follow installation instructions and will easily get you within the required fuel delivery parameters to get the most out of your new Cobra exhaust.
