4in to 1 change ?

Rod when i had my Gen2 when i changed from standard exhaust to a 4to1 it made a big difference bike ran a bit rough and wasnt smooth in terms of power delivery. once i had it tuned it was good again. i imagine going backwards would be much the same. are you looking at putting standard headers back on with slipons or an aftermarket 4to2system? you could sell the PC's off to fund the flash just a thought.
