Cobra 4" Slip On Mufflers For Harley

These award winning slip-ons for Harley models 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 mufflers, super-heated gasses get a chance to cool before exiting the silencer core making Cobra Dresser mufflers virtually blue proof.


  • Welded from mild steel then bathed in a four-step chrome-plating process
  • Increase horsepower and torque with a deeper, more aggressive exhaust note
  • 4" muffler bodies use a cooling chamber with proprietary technology to prevent bluing
  • All necessary mounting hardware and instructions included
  • Made in the USA

Note: Headpipes sold separately.
