I'd be interested in hearing your opinion on them. Do you think the Arrow worth the price difference? Is there an obvious quality difference between the 2?
I did not pay much more for my Arrow headers. So for me the price was no issue.
Arros uses a different design (like Akrapovic headers) than Black Widow.
The fitment is better (read: not as bad) for Arrow compared to the headers from Black Widow.
That is to be expected as Arrow uses "spigots" and slide-fitment vs Black Widows headers using tubes from exhaust port to colllector like OEM.
(OEM is even in one piece from headers to end pipe).
Black Widow do not use "link pipes" between header pipe, which I like, as this is an area that can develop leaks/false air for WB-sensor. The same goes for spigots/slide-fit (to the exhaust ports).
I have the habit to try out different exhaust, because I just like to "mod" during the (long) winter where I live.
I will be able to report more about what I think about Arrow vs Black Widow when spring is here, and I can test the bike.
