Can anyone identify this blaster pipe

[Big Kahuna]

John Quast at Speedwerx would probably be able to tell you more. The coupler and mounts look a lot more like the Coffman's but the shape is very similar to a Speedwerx expansion chamber (without the outer water jacket).

Both the Speedworx and Coffmans pipes looked similar.

Pretty sure that's it. From what I can see in pic. He's needing to know so he can find out specs to set his carbs and also buy the mounts. Thanks for help!
