...maybe a little more info about the type of bike, what you are going for (sound, performance, look?), etc.How is that Baak exhaust working for you? What did you do about the o2 sendor cables? Did you have to remap? I also heard about fatduc o2 manipulator. What did you do? I'm want to pull the trigger on the baak bobber exhaust but want more info. Please advise...
