Anyone running black widow mufflers

[Aarons Air]

Black widow has several muffler sizes. I have a 68 coronet, and am trying to choose between their venom 250 series (9"x14"x4"), and the shorter race venom muffler ( 9"x9"x4"). Has anyone here ran either of these ? I am curious about sound and fit of each. Thank you.

I haven't run them on my own car but I do custom exhaust at home and I have installed them on several cars. they sound really good, I have been told by the customers that the 250 series have less drone then a 40 series Flowmaster. The race series is ridiculously loud. They have a good tone but they are pricey also.
