Wow!
That's a good price My Little Bro has one on his R6 and it's not bad quality. Obviously, they are not in the same league as Sato, Akropovic ect but if it's just looks and sound you are after I can't fault them.

My new ride is a bit of a Howler and I love to make her Squeal
I have Beowulf Tri-oval Warriors on my Suzuki 1400 (Microns on my VTR), so can only speak of experience from the Zooki side, but have to say that they are very well made, top quality stuff, and the sound from my Zooki is a nice rich deep mellow roar, not harsh on the ears, how shall I put it - pleasantly loud but not offensive. And service from Beowulf is top notch.
I'm also thinking of putting a set on the VTR to replace the Microns, so would be interested in what you think if you do go the Beowulf route.
