Hi Monkeyhanger,
Thanks for the advice. I'd be very keen to hear the Zard in person. I'm just a bit worried it has a slightly whistley or chirpey note to it. The custom underseat (MV rip off) exhaust I had made for my '02 seemed to sound very similar and it got a bit annoying after a while. I'm chasing a quite mellow, deep, bassy type of note. Don't really like the raspy sound others go for or the popping on overrun. I also love the look of the Arrow to be honest.
The other option I'm seriously considering is just having the stock cans gutted and a standard perforated core with fibreglass packing added.
The third option I've thought of is bodging a set of those gorgeous new Akropovic hexagonal carbon jobs into place. Not sure how the bike would run with them though.
I guess I should wait until I actually get the bike though.... ;-)
Phil
