I've read alot of threads but no one has ever mentioned whther or not a catless setup will throw a CEL or service engine soon code? I'm considering a mac catless O/R H pipe, but don't feel like screwin w/ a thrown code

definitly will cause a cel, you need mil (malfunction indicator lamp) eliminators.

something like that. or if you have a tuner you can turn off the o2 sensors.

yep. sure will. Just pick up some mils for like 40 bucks or make a set of your own for much cheaper.
