exhaust questions

[lil_watz_ex]

I am thinking about switching out my white brothers exhaust for a hmf and was wondering how much this would affect the jetting of the bike. The white brothers is a full exhaust with no packing left and the inner core rusted out so this is why I am thinking of getting rid of it. would this make much of a difference as far as jetting and preformance? thanks in advance

I wouldn't think there would be much difference. I swapped out my White Bros for a Lexx and didn't have to change any jetting.
