Overview of Thunderheader Black Thundercone Slip-On Muffler - 1069B

  • Fits single-side OEM 2-into-1 system
  • Increased horsepower, torque and unmistakable Thunderheader sound
  • A patented collector is used instead of a conventional baffle in the muffler
  • The Collector is designed to direct spent gases through four acoustical dampening chambers
  • The flow director serves a multi-task function: directs outgoing flow through four acoustical dampening chambers creating a spiral motion upon exiting to atmosphere and it also forms a pyramidal shaped anti-reversion trap to minimize the amount of air rushing in
  • In conjunction with the flow director, a diffuser shroud is built into the reverse cone, this patented device is designed to diffuse the air rushing in as the pressure inside of the system becomes equal to atmosphere


  • NOTE: Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that need to be made during, or after, installing their product. If a jet kit or fuel processor is recommended, see our Intake/Fuel section.

    Exhaust discoloration (bluing) is caused by engine conditions such as cam timing, fuel-air mixture, operating temperature, etc. It is not the result of defective manufacturing; therefore it is not covered by any warranty. See our Chems/Lubes section for products to help remove or prevent exhaust discoloration

    Included Items:
    (1) 28 1/2 in. long black slip on with non-removable baffle

The Air Resources Board (ARB) does not permit the use of aftermarket emission-related parts that alter the air/fuel ratio of an emission-controlled vehicle. Due to these legal restrictions this part cannot be shipped to California.

The muffler arrived with a few rub spots where the flat black paint had rubbed down to metal. Exchange was easy and customer service very helpful. And it did not come with hardware needed to attach it to the bike. I had to order a mounting pin, nut, and isolated from the Harley Dealer before I could install. But once I put it on and started the bike...Nice! It's sort of loud, louder than stock for sure, louder than screaming eagle upgrade too. But it's a nice rumble sound, not just loud. It really does sound like thunder rumbling. It hasn't seemed to change the performance of the bike, maybe a machine could detect a change, but I really really like the sound. I do recommend buying the ThunderCone slip-on muffler. I love the sound! Idling, accelerating, cruising....and downshifting too. It's great!

I left a 3-star review due to shipping problem causing a blemish. Now I want to review based on actual installation and use - but how?. It's an awesome muffler. Thunder sound really.
