I'm sure this has been cussed and discussed multiple times but ive been unable to find one that gives me a full answer. Any info will help. I've owed 2 gixxer 1000's and 4 R1s and just bought my first 10 last week! Love it so far. I'm trying to figure out what I should do with the exhaust. Questions. On average, how much additional gain do you get with a full system vs. slip on? I guess another way to ask this is how much do those big cats on the head pipe slow things up? Do you have to remap with both or just the full system? Thanks!
