Hey guys wounding if any of you are running a m4 slip on with a custom map? If so will you share it with me?
Never tried the LOR, I have the Leo Vince GP slip on currently. It is far quieter, but also has the boom box back on there. There is tons of power, probably more than the M4 up top as well as down low. As much as I hated to put the boom box back on there, the bike runs a lot better. I will replace it with the Akra link pipe though as soon as I have the funds, right now I spend all my money on track days...thanks bird_dog!!! when comparing your M4 and your LOR what differneces did you notice?
