Yes, CF mufflers sound awesome.
And yeah, you gotta get rid of the udder. This pretty much sums up my opinion of that ugly thing:
Not to ignore Marvel... the Quat-D ExBox looks bad-A.
I think because it's shaped like... well, a stylish motorcycle part, instead of looking like a malignant tumor. And I do loooove how much it cleans up the tail of the S*R-series bikes. I haven't ever heard one in person, though (and I trust no video + PC speakers to make that determination), so I dunno whether I like their sound.
