Blue Gpz 1100

I had a track day last year after an accident on bike here are some photos.

I'm thinking about getting an aftermarket exhaust for the GPZ and would love to hear any input from the gang!

I would prefer to keep it a dual (one can per side) setup, but I have only seen 4 to 1 systems. I'm fine with the single can if that's all that there is though.

I am hoping to get a throatier sound with a tad more volume but not obnoxiously loud. Any performance increase is great, but not quite necessary and not as important.

I've seen a great deal on a Vance and Hines ($350-or so) but hear great things about the muzzys (600-900 depending on material).

Thoughts?
