Im looking at fitting some aftermarket cans to my 99 model.
Im going for the exhaust cans and the mid-pipes, ie, changed from the footpegs back with less restricted exhausts.
Q - Do you need to fit a power commander on and 1/2 system?
Depends how far out fueling is .......... most times a yosh box tune will bring it into correct A/F range
Q - How can you tell if you require a PC after fitting pipes?
Your fueling will be out even before changing pipes, it's also not so much you need a power commander .................. you simply need a means of correcting A/F ratios (Yosh Box, PC)
Q - Will the oxygen sensor see that there is a change on flow and re-map and correct the ECU its self for the new exhaust?
It won't because your bike doesn't have one and even if it did as in the Gen II then once it goes into open loop, in effect it also doesn't have one
Q - If i require a PC, what is the best model or the correct model PC for my bike, Gen 1 1999 model.
Should be plnety good second hand units around to suit the 99 model
Q - And if anyone knows a good mech, dyno or tuner in the great western sydney to assist me with the upgrade?
