Some people say yes..it's okay---most say the 02's will mess up....I believe the latter in most cases..although haven't done it myself....most also say attach a 12" section of pipe to your header and that should be fine.

i ran my kooks open, dumping straight from the collectors, for a couple months. some huge speed bumps ripped my y-pipe pretty good and didnt have the money to fix it at the time. ungodly loud but only increased ~1mpg when i put the pipes/muffler back on so i dont see it affecting the 02s.
