ied or xied?
 

Getting ready yo put Vance and Hines HS slip on mufflers on my 07 Street Bob. Should I go with the IED's orthe XIED's from nightrider? I assume the A/F ratio with the IED's would be adequate.No mods to intake yet.

I ordered the xied's for my 07 883, only Python 3's now, and immediately got a check engine lite. Stephen at nightrider sent me the O2 ieds and I put them on and no problems. I am gonna put the SE A/C on today and retry the xied's. He told me it might be an exhaust leak causing the check engine lite. But he is very easy to work with. Go with the xied's and see what happens. He said this problem is mainly with sporties. Hope this helps.
