I have a friend who has S-model and he is selling his slip on Termis to me as he just bought a full Termi system. (he is just swapping out the header pipe and selling the other parts to me) I have a base model and am asking if I can use the slip on's for a S-model on my bike? thank in advance

probably not - The ECU for the S model will have all of the programming for the DDA and DTC.
Your bike will not be equipped with the sensors and hardware that the ECU expects to see.
I'm guessing that the ECU will give you a check engine light at the very least and at the worst fail to operate.
