Datona Performance exhaust header (4 into 1)

Anybody hear of Datona Performance Exhaust?  Just removed this off my bike.  
Only thing I don't like is that it covers the oil filter area underneath.  

A simple GOOGLE search turns up nothing and yes no “y” in this Datona

Yes I have heard of that pipe.  If I am not mistaken it was one of the pipes tested in the Cycle mag from  1978 done by Cook Nelson back in the day called the power pipes.I think there is a post/link here somewhere but if not I do have a copy of it if you are interested.  Let me know and I will post what I have.  I am sure others will chime in with what they know.

Thanks for your reply and please post what you can. Looking forward to learning more about what I have!

Ok  I did a quick and dirty search and did not find the post  was thinking was here.  If I have post this and it is already here then I am sorry.  But here is what  have .

Had to splilit this up due to size
 

The last of it 

I sandblasted my Datona Performance header and then painted it with VHT primer and then a couple coats of VHT Aluminum.
I also wrapped the baffle with a fiberglass sound deadener product.
 

Nice work!

That pipe certainly inspired by KerKer Megaphone...
