That look fugly imo. I can see why they've done it tho - very motogp stylee. Prolly sounds good too. But in terms of looks - it's very cheap and nasty looking.
From probably the best looking exhaust you could fit on a blade, to without doubt the worst. I loved the look of their original Taylor Made exhaust, it looked like it was part of the bike, quality could have been better, but looked great.
