if you're worried about emission inspections, go cats. If you're not, go no cats. I went with the Solo hi-flow cats where they relocate the o2 sensor further aft to help prevent a CEL code. I also picked up about 20 rwhp with them and great sound improvement too. I'm really happy with the solo's. I have a friend with LT's with no cats and he has gone to 4 mechanics (including mine) and can't pass emissions. At least in NC there are inspections annually and you must pass to renew your registration. maybe it's more leniant in MI. best of luck to you.
