Switched up my exhaust from a Spintech Pro Street 6000 3" in duel 2.5" out for a Black Widow Venom 250 3" in/out muffler, no flapper, no resonator, 3" pipe back, and a 3" in 3.5" out tip. I did like my Spintech muffler but I have to say the Black Widow is more me. Here are some videos to compare.

Personally I have never liked the single in and dual out mufflers because they just don't sound good to me. You get a lot more bolder sound not to mention power from a single in-out pipe. Good choice going to a single in-out setup.

I am very very happy with the Black Widow muffler. Glad I made the style switch also.
