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
