Was happy with mine initially...after 1.5 years...its started falling apart... the welds on the hangars broke off....tore a hole in my exhaust...this caused droop...then the welds around the resonator broke..
I hate to be "that guy", but I've got the exact same issue Rusty is describing. I'm really happy with the exhaust sound and initial build quality, but I'd really like to get this addressed. Maybe Enthuza (Jason?) can chime in.
While I kind of doubt this group buy is still going, I've had that lightweight XR on my NB for probably 4 years now, and it's still going as good as ever. I also bought another Speedster or something from him before that which was also great quality.
